Just wondering what the general concensus is on DVD playback on the 360? Mines pretty poor. The image jerks and lipsynch is out. But the sound is ok. For the record, thanks to another thread I've established I have a Hitachi drive in my 360. Could it be linked to that? It's the only thing I'm dissapointed about with the 360. For such a powerful machine the DVD playback is shocking.
