Volume problems with Dual PVR-250 cards
I have been using mythtv versions 0.17 and 0.18 on a Pentium III 800 MHz 512 memory, using 2 x PVR-250 cards.
My sound card plugs into my RCA Home Theater sound system..
Normally I just need to set my RCA to 30% sound volume and my PVR volume controls to 30% (for Music, TV, Games ).
Lately I purchased a spare 300GB hard drive and substituted it in my machine and tested the Mythdora 2.1 on it.
I installed Mythdora 2.1 onto the new 300 GB disk and completed the configuration every thing worked (mythgames, mythmusic, mythtv)
One problem, The sound volume in mythtv
Example
Listen to music set RCA volume to 30% and mythmusic volume 20%
Play mythgames set RCA volume to 30% and mythgame volume 20%
Watch tv set RCA to 55% volume and mythtv to 90% - 100%
I have looked at my recording properties in mythtv and veried the record volume is close to 100% for both tuners. Still volume is too low.
Can you shed any light why volume control is so different between mythtv (0.17, 0.18) vs mythtv 0.19
I have removed my 300GB and restored my primary drive back. My volume is once again perfect using Mythtv 0.18 version.

Problem with msp3400
I logged this issue with IVTV. I did not have the volume problem with FC3 and mythtv 18, but when I switch to mythdora and FC4 the volume problem surfaced. Here is what trac said from IVTV (Took a few months to get a response to my ticket)...
* status changed from new to closed.
* resolution set to invalid.
Caused by a change in the msp3400 module in the 2.6.15 kernel. With the 2.6.16 kernel this should be working again. It's not an ivtv bug.
Well let's hope that the new
Well let's hope that the new 2.3 version will work better for people on this as it uses the 2.6.16 kernel.

I found the volume a little
I found the volume a little low too.
I have a PVR250 and a PVR500.
So in my /etc/rc.d/rc.local I add these commands that bring up the volume at startup :
ivtvctl -y volume=65530 -d /dev/video0
ivtvctl -y volume=65530 -d /dev/video1
ivtvctl -y volume=65530 -d /dev/video2
