iPod resets when playing movie

So I just picked up my Composite AV Cable for iPod Classic and tried to use it to play a movie (Shaun of the Dead) that I had converted with Handbrake for iPod format. This movie has been on my iPod for a while and I've had no problem playing it before. But now that I've connected the Composite AV Cable, the iPod will reset when I select to play Shaun of the Dead, regardless if the cable is connected or not. Other movies & TV shows (purchased from iTunes, ripped from DVDs, and recorded & exported with EyeTV) work fine. The only difference with Shaun of the Dead is that it doesn't have chapter markers. Is there an issue with iPod Classic & the Composite AV Cable playing movies of a certain length without chapter markers?
