Must be a password/user problem? how can I check it?

In the process of trying to do a clean update from the Mythdora repositories as outlined in the original posting, I found that some of the mirrors listed in http://mythdora.com/mirrorlist/10/updates-x86_64 are incorrect. It reads:

#http://dl.atrpms.net/mythdora/updates/10.21/x86_64/
http://devel.mythdora.com/mirrors/mythdora/updates/10.21/x86_64/ # this timed out
http://mirror.beww.org/mythdora/updates/10.21/x86_64/ # this does not appear to match the others
http://mirror.wilsonet.com/mythdora/updates/10.21/x86_64/
http://www.radioactiverussian.com/mirror/mythdora/10.21/x86_64/ # This only has 0.21 packages

ftp://mirrors.dotsrc.org/mythdora/10.21/x86_64/ # This only has 0.21 packages


I ended up creating a local file as shown below:
(note the addition of "updates" in the last 3, and the exclusion of "mirror.beww.org")...

#http://dl.atrpms.net/mythdora/updates/10.21/x86_64/
http://devel.mythdora.com/mirrors/mythdora/updates/10.21/x86_64/

http://mirrors.dotsrc.org/mythdora/updates/10.21/x86_64/
ftp://mirrors.dotsrc.org/mythdora/updates/10.21/x86_64/

... and edited the "mirrorlist=" line in the mythdora.repo file under [mythdora-updates] to point to the local file. This finally got a useable upgrade (from the Mythdora repos only) in place.

Still no joy on the problem I'm having with mytharchive (see this thread in the Usage Forum for details).

I was greeted with an odd message when I rebooted my machine today. It was a message prompting me to upgrade my music database schema. I had thought nothing of it and just allowed it, but it turns out that Mythdora upgraded Mythtv to 0.22 without me realising it. I can only imagine it was part of the file upgrade Mythdora prompted me for yesterday. But the problem is that I was using one of the themes that were deleted in the upgrade. Now Myth won't start because of the missing themes that the database is still pointing to. It just errors out with this message:

2009-12-08 22:41:45.855 WARNING: The theme (blootube-wide) is missing a themeinfo.xml file, ignoring.
2009-12-08 22:41:46.873 Error loading image to scale, from file: /usr/share/mythtv/themes/blootube-wide/
Floating point exception

Is there any easy way to fix this, or am I going to have to reinstall?

Being the Linux neophyte that I am, I think I just navigated to /usr/lib64/mythtv/plugins/ and deleted (or re-named) libmythstream.so.
But monir811's solution is more eloquent.

Syntax is rpm -ev package_name

On my installation I ran:

rpm -ev mythstream-0.18_1-22.md10.x86_64

I just finished my upgrade of mythdora 10.22 x64 that ended with no problems. After a reboot, it was able to upgrade the database for each function. The blank gray screen was a bit misleading at first, but I tailed /var/log/mythtv/mythfrontend.log and saw that it was working :) Thanks again!

I performed an update as suggested but some of the menu items say the associated xml file could not be found. I was able to access and run a backup and watch live tv but options to access setup or some of the other menu items fail.

I also checked the settings table and 'ThemePainter' is already set to 'qt', and 'Theme' is set to 'Terra'. I then checked the path the theme is looking for files and was surprised that the files in questions really do not exit.

First, thanks for the guide on upgrading! If you have an nvidia adapter, going to VDPAU is a MUST! went from 100% cpu problems to less than 10%. Much less skips in HDTV OTA viewing. Also, make sure to remove mythstream because it wont work with 0.22.

Has anyone had the problem with the TV guide where, when going to it, the PIP displays in the corner then mythfrontend goes to 100% cpu for 5-6 seconds then the guide appears, constantly blinking? Looking in the mythfrontend log I see several entries of this during the 100% cpu:

NVP(0): Timed out waiting for free video buffers
NVP(0): Timed out waiting for free video buffers
NVP(0): Timed out waiting for free video buffers

I've tried to find ways to fix this but none of the advice on the net has worked. switching from GL to QT effects doesn't change behaviour.

I decided to go for the 0.22 update on my well running 64 bit 10.21 system. Removing mythstream took care of the floating point problem. My database that I backed up simply would not upgrade to the latest schema. Also, I really needed to get rid of a few of my tuner devices that had been removed and replaced enough times that my two cable via firewire boxes were numbered four above the highest DVB.

Solution? Wipe the database, create a new mythcoverg, set the encoding to latin, NOT utf8 and then after setting up mythtv, do a partial restore only. This will keep your recorded programs and recording rules intact and you will still see your previously recorded material with all of it's info. I got this from the mythtv wiki. This is the first part:

mysql -p mythconverg

DROP DATABASE IF EXISTS mythconverg;

CREATE DATABASE IF NOT EXISTS mythconverg;

ALTER DATABASE mythconverg DEFAULT CHARACTER SET latin1;

quit

Ok, now that you have done this, go into mythtv setup to create one. Go ahead and set up your hardware to your liking. After this, do a partial restore:

mythconverg_restore.pl --partial_restore --directory /storage/dorabackup --filename mythconverg.sql.gz

I'm not sure why or how I wound up with an older schema database that had duplicate entrys which caused the upgrade to only go to schema 1230 and give up at 1231. The other method would have been to edit the database until it would take a full schema upgrade and this is not trivial.

Just to make 100% sure before I go ahead, due to WAF and all - what are the default repos for MythDora?

I have the following in /etc/yum.repos.d/:

fedora.repo
fedora-updates.repo
livna.repo
mythdora.repo
rpmfusion-free.repo
rpmfusion-free-updates.repo
rpmfusion-nonfree.repo
rpmfusion-nonfree-updates.repo

..although I don't think I've upgraded anything outside of mythdora since install

Also - should I do any updates prior to enabling rpmfusion-testing?

cheers

I tried the upgrade on my test PC. I found that in the capture card setup .22 uses IP address to ID the HDHomerun. 10.21 used MAC. At first I didn't think this was a problem. But after a 17-hour power outage last night interrupted my setup, I found that my router changed the IP address on the HDHomerun (DHCP). So, everytime I have a power outage I may need to re-run setup? I don't know if there is a way to set static IP on the HDHomerun (I did set static IP on my mythbox). Any ideas?

Hi,
I've tried this on a 64-bit installation and everything in the back-end setup screens seemed to go fine. On starting the front-end it requests to convert the database to the new schema. Once this had completed and the front end restarts I get the 'floating point exception' error.

I did a full re-install from scratch and just selected the mythdora update repositories to ensure no additional packages would be added and still received the same error.

I went back to using 10.21 but yesterday the system updates installed the 0.22 packages with the result that the floating point exception has returned when re-starting the front-end.

Is this a problem with the 64-bit version that is being investigated and will soon be corrected or should I downgrade everything to 32-bit ?

I have done the upgrade following the instructions but Mythfrontend seg faulted on first run. Following is from logs:

Does anyone have any ideas where I should start looking.

Tanks in advance.

Tried this on x86_64 and got the floating point exception error. Did a fresh install with the 32-bit flavor and everything went smoothly. Thanks for the guide.

MythDora is definitely the pick of the distros if you are looking to develop a HTPC.

I have a very successful HTPC based on Windows XP and MediaPortal which is very close to commercial quality in reliability of operation, probably better than a lot of commercial offerings.

Now I have the desire to develop a second HTPC based on Linux. I am still learning the basics, do not want to use that disgusting "N" word, which seems to guarantee a non reply in a lot of Linux forums, or if a reply is received it is usually aimed well above the enquirers knowledge of Linux. Definitely not saying that about the MythDora forum, though. I have about 40 Cd's, DVD's of different Linux distros, sitting besides me, that I have tried, and have read through a lot of Forums.

I guess, like a lot of people, I was really excited when I discovered Linux, and thought yes, I am going to conquer this, plus I feel that the Linux OS's are more responsive, and quality of graphics is better than Windows. The TV picture quality on my computer monitor seems better than the Windows system, which is why I am persisting.

Anyway, I have MythDora set up to do everything a HTPC should do, even have sound from my Sound Blaster X-Fi Xtreme Audio sound card , more by black magic, than a knowledge of Linux. The only feature I have not achieved, as yet, is for the system to wake up for recordings. I have read quite a few articles which mainly seem to originate from 2007, and seem quite complex. From my experience it seems that if these systems could be made to reliably wake from hibernation, the solution would be a lot simpler. I have found that with Linux distros that will wake from hibernation, this feature seems to disappear with the addition of hardware, for example, my NVIDIA 7600 graphics card.

I have installed the upgrade to MythTV 0.22 RC1, using the excellent instructions supplied by Ryan, thanks, and have found the following, so far,

Had to change QT style to CDE or Windows to be able to read screens.

Had to change zoom to half with 4:3 aspect ratio to properly fill screen in TV Playback, on my computer monitor.

in MythTV when trying to delete a recording, system goes to the watch recordings screen.

I also, do not particularly like the selection of skins, prefer ProjectGrayhem or the old MythBuntu.

I have installed the latest NVIDIA driver, 190.42, and can supply instructions, if anybody needs help in this regard. Only problem, it seems to have affected my sound, it is now a lot quieter than it was and varies dramatically from channel to channel.

The other existing issue, before the NVIDIA upgrade, was when I connected MythDora to my 42" HD Plasma. I set the resolution to 1920 x 1080, which is fine, but when I restart the system it defaults to Auto with a resolution of 1280 x 1024. Does the same with my 19" BENQ LCD monitor, and this is not the native resolution for either. Using the save to X Configuration File button on NVIDIA X Server Settings does not work, just get an error message. Managed to do this using a command line, still returned to Auto setting and 1280 x 1024, very annoying.

One other issue was to get MythDora to recognise my WD Passport External drive, I had to reformat as FAT, then when trying to copy a movie file it would only copy 4 GB of the file. I have played recordings made on MythDora on my MediaPortal HTPC, and the quality is better than those made on said HTPC. In saying this, the recordings on MediaPortal are still very good, as least as good as the original Samsung TV Picture quality, if not better.

Install went fine here.
Fresh install of 10.21 on new hardware. Imported old database backup, upgraded to .22.

Over all I like .22. There are some glaring UI color problems tho.

In every menu theme it is VERY difficult to see what setting you have selected. The difference between selected and not is just a 1 pixel wide line that changes color.

The font color in several of the themes is BAD. Mythcenter Light Blue on white for a text box?!?! How the hell you suppose to read that? Mythbuntu black text on dark striped background?

ALso under the setup > appearance menu. If you select classic menu theme you no longer can reach some of the menus. you get a file not found error. You have to go into mythweb setup and change that setting in the database.

All of these are upstream problems and not the fault of mythdora. The solution is to go into the theme files and change some colors or get some older themes installed.

Other than the theme related problems this version is NICE.

I have a mild form of Dyslexia that affects my ability to spell. I do use spell checking to help but it does not always work. My form of Dyslexia does not affect my reading. Dyslexics of the world untie!

I am trying to upgrade my system, but when i try to run mythfrontend it won't run... an error message appears "floating point exception". any Suggestions ????
