[mythtv-users] Green boxes on one DVD's playback

[Ian Evans]

Picked up two series DVDs the other day. One played flawlessly on my
Mythbox. The other had these chunky green squares flashing on the
bottom right of the screen. Though I could eventually get to the menu,
the episodes were all scrambled up.

This is the first time I've encountered an unwatchable DVD. Doesn't
appear scratched at all. Any ideas?
