I'm surprised at this. Lots of tools that can "play" an mpeg2 stream with errors OK, but can't transcode a stream in a fault tolerant way. Sad, if true. BTW, I *do* use (digital) cable and I get these errors all the time. I get very unreliable service from my cable provider (Hi, Comcast!), even though I've complained to them a multitude of times. (Peeve: frequently the cable signal quality gets poor, and my digital tuner won't reliably accept channel-change signals from the RS-232 port because it's busy trying to send info back to the cable company and can't handle the bad upstream connection. So, to fix this, my channelchange script actually daemonizes and makes up to 5 attempts at changing the channel - a value I found could reliably change the channel in case the signal quality gets poor. It sends an extra "back/exit" after each three digit channel number, so that in case it missed a digit I don't go to channel 070 when I'm trying to go to 007. This, in an effort not to miss scheduled recordings just because those fartknockers can't keep the signal level clean. But I digress...) There *has* to be a way around this sync problem. Tell me this: does the mpeg2->mpeg4 transcoder in mythtv fix the sync issues in the PVR-x50 generated streams? (My PVR 350 won't play mpeg4 very well since it has to use the slow framebuffer.) If so, couldn't I then just transcode mpeg2->mpeg4->mpeg2 and end up with a playable file, in the sense of playing on the PVR-350's output as well as something still convertible to DVD format that remains in sync? How would I go about doing that, in particular going mpeg4->mpeg2? I figure if I could get that done, then I could easily script it to run as a user job, so that by the time I intend to record something it will likely be in a form that won't give my DVD player, scripts, or me heartburn. (FWIW I also tried lopping the file into a few pieces using dd, but that was, err, unsuccessful. ;) I promise if anyone can help point me towards a solution, I'll post any successful results I get on this list, as well as how I did it. I might even buy you a beer. ;)
