Well... Not perfect yet, but much much better than ever before!
A problem I noticed with one of the very few discs I tested is this (Die Hard 2):

Startup of DVD->20th Century Fox animation -> Animation of 20th CF logo, airplane in snow, interior of control tower ->Static menu with options to 'play movie' or 'select scene' (=Main Menu) -> Choose 'select scene' -> Animation while going to other monitor in control tower (I call this animation A) -> Static menu to choose scene or go back to main menu -> Choose go back to main menu -> Back in main menu.

Everything is fine, until we are back in the main menu. Now using the cursor keys to go from one option to the next responds very slow (0-5s). Also, when choosing again to go to the scene selection menu, the animation A is played back very choppy. Menu navigation in the scene selection menu is very slow as well now.

It seems as if cpu-load suddenly gets very high at some point. Stopping the dvd and restarting it solves it, but doing the sequence described above make the thing go very slow again, so the problem is reproducable. While checking with top command, it doesn't seem to be CPU-load...

Thanks for this outstanding piece of work!

Thanks for sample file. I'm able to reproduce the slowdown.
CPU is actually low (~20%) when it goes slow.
No ideas yet, but I'll investigate.
