If you're transcoding, you should be using something suited for that purpose, like ffmpeg. Enclosed is a shell script that I use for transcoding arbitrary videos to DVD format. Feel free to change the framerate, frame size, and aspect ratio to any legal values.
I use mpeg2enc only for creating MPEG2 video out of analog streams. ffmpeg can
do that too, but mpeg2enc is MUCH better at it.

mjpegtools-2.0.0-1.fc16.i686
My question is if mpeg2enc is able to convert
mp4 videos to mpeg2 dvd format. This is how I am invoking it:
$ mpeg2enc --no-constraints -o video_12.dvd <
$PWD/Video_12.mp4
INFO: [mpeg2enc] SETTING EXTENDED MMX for MOTION!
INFO: [mpeg2enc] SETTING SSE and MMX for TRANSFORM!
INFO: [mpeg2enc] SETTING EXTENDED MMX for PREDICTION!
**ERROR: [mpeg2enc] Could not read YUV4MPEG2 header: bad header
magic!
$ file Video_12.mp4
Video_12.mp4: ISO Media, MPEG v4 system, version 2
The mp4 video plays just fine using ffplay, mplayer, vlc, ...etc
on Linux.
Thank you.
