OK, when I run midentify on the mpg file, I get 128, 8192, and a52 for
ID_AUDIO_ID, ID_AUDIO_FORMAT, and ID_AUDIO_CODEC, respectively. I can
play the mpg file using mplayer and it works. The sound seems to be
slightly behind the video though. I'll try making a DVD of it later.
When I do, will Mytharchive try and use the nuv file and, if so, how can
I tell it to use this mpg file that I transcoded using mencoder?
Thanks again for the help!
