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!
