repair choppy mpeg2

I have a pvr250 and I'm running a relatively recent version of myth that I
grabbed from CVS on Dec 8th. I recorded a show yesterday, and the
playback is very choppy, and it ends up playing back at about 1/4th speed
as a result. Is there any program out there that will fix this? Maybe
either fix the choppieness, or re-encode the file? I can deal with
glitches, but it's really bad right now. Ideally I'd like to do this
offline on another machine that's much faster, but I don't have to do it
that way.

Thanks,

Nathan

Current IVTV & Myth dont seem to work well together, the only real fix
that totally fixes everything (lockups, ghosting, tinny audio, and
skipping) is to go back to cvs's on both dated ~1 November.

There's patches for Axboes latest version that fix the tinny audio, but
leave the terrible ghosting.

Recording at 704x480 used to fix the ghosting, but that does not work
either, on the current version of myth & ivtv. Downgrading everything
does work well though, if you can live without the newest features.

Hey MegaDeTH,

Are you sure about this? I am running .13 with the patched Axboe driver
and have seen no ghosting at all. Are you sure your using the latest
firmware (21288 or 21337)?

Yeah, everything is peachy here, running the Axboe/Anduin patched driver from
11/25 with MythTV 0.13 and firmware 21288. One PVR-250 and one M179 in the
same system.

I used 21288, I was not aware there was a new version, ie 21337 I will
try that one after the holidays, i'll be gone and I dont want to risk
missing recordings.

Hmm, I just double checked the firmware version ... they are all the
same! 21282, 21288 and 21337 all extract out to the same images?

So no rush. I guess you need to look elsewhere for your trouble.
