I have interlaced h264 files in an mp4 container, which an can trancode 
the following way
MP4Box -raw 1 nameof.mp4
MP4Box -raw 2(wanted audio-channel number) nameof.mp4
after that you have nameof_track1.h264 and nameof_track2.ac3 (or other 
extension which depends on the source of your audio track.

I transcode these raw files with ffmpeg, but mencoder will also be 
possible to de desired, in your case dvd-format.

Hope it helps
