i'm adding dvd menu support to the mythtv project and ran into the problem

I wanted to get advice and/or opinion on the following patch I use to
address this issue.
my ultimate goal is to find some way to detect that the video stream has

only clue , from a mpeg perspective,  I can find is the dvd produces the
mpeg sequence end code when it's in a

If someone has any other ideas, please let me know. I'm kinda new to mpeg
programming so any advice or direction
on this matter will be helpful.
