Gary, I am seeing similar problems myself. I am using a Hauppage Nova/T dvb card, so the .nuv files are pretty much straight MPEG2 files. I use either dvb-mplex or replex to re-multiplex them and then dvdauthor to create the DVD structure. I find that dvdauthor complains about incosistencies in the audio, and sure enough the audio and video get out of sync as you go through the dvd. I have found that BBC channels work OK, but that ITV and Channel 4 don't. I haven't done extensive testing on this, so it might just be a coincidence. One thing I have noticed is that replex reports: Wrong audio frame size: 1072 Wrong audio frame size: 656 For ITV channels. Could that be related? Have you tried doing this for BBC? And are you using a digital or analog card?

I'm running knoppmyth, with mythtv 0.16, and the latest versions of transcode mjpegtools available from apt. I'm also running the latest nuvexport (27/12). I've checked my audio recording settings and they are at 48khz I found one snippit of information which suggested running mpeg2desc -m on the .mpg file to determine the audio offset, and then using that information to reencode the file. Any ideas? Thanks Gary |
