MythArchive not adding closed captions as subtitles

Hi everyone,

I am having difficulties burning DVDs with subtitles. I can see the closed captioning when playing back the recordings, but when MythArchive processes the cut list, I see the follwoing message:

Didn't find any subtitle elements in stream info file.

I am running Mythdora 10.21 x86_64.
My recording hardware is a Hauppage PVR-350. Video files are MPEG 2-PS.
I have checked Use ProjectX and Add Subtitles.

If anyone can point me in the right direction, it would be great.

Thanks in advance,

Beny
