[mythtv-users] Can't play recordings made pre- PVR-350 TV out

Over the weekend, I finally gave up trying to get the lousy 
proprietary ATI fglrx driver working with my on-board ATI 9100 IGP 
chipset TV-out. Their driver apparently doesn't support DRM or GLX 
video sync timing, leaving me with only RTC, which skips every few 

Anyway, I'm now using TV-out on my PVR-250, which works pretty well. 
The problem I have is that some (but not all) of the programs I 
recorded previously now won't play correctly. They display about 
every-other frame, very jerkily, and there is no audio.

I'm using the same resolution as before, 720 x 480, but the videos 
that won't play give me a whole slew of errors having to do with the 
framerate being incorrect, and no XvM available (*is* there such a 
thing as XvM for ivtv-fbdev?) Oddly, I looked in the files' headers 
with a hex editor, and they do seem to be at the correct resolution 
and framerate.

BTW, I'm using Myth 0.16, downloaded from CVS on Friday.

Are there utilities I can use to display the headers of both working 
and non-working files, to more easily compare them?

Is there some way I can, perhaps, transcode these videos so that they 
will work with the new TV-out?
