Anybody else have this problem?

[weezee]

I have this problem with Enter the Matrix. All the sound is out of sync, no matter what I patch. Instead, LotR - The Two Towers has terrible frameskips in every movie scene. I tried it on TDK at 2x and 1x, but it jumps frames&sound everytime.
I fear it's a matter of DVD reader, which is different and very unreliable in every Xbox.
