Well, I'm pretty sure that this DVD was running perfect with
earlier versions (it's one of my favorites). But as I didn't used
DVD feature for a longer time, I cannot say when the problem
started. Which was the last version without liba52? May be I
could get hands on it and give it a try.

Yes, this was my fault. I used a old driver with klaus
iframe-patch which seems to make the menus unusable.

Right, I updated to 1.1.1, but it doesn't changes anything.
