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?
