My problem with HD-DVD may be due to my player (XA1, latest firmware) but I doubt it. I have absolutely no problem playing new discs. Some rentals with scratches play without problem but some with couple minor scratches do not. The last disc I had problem with, Derailed, looked pristine (after cleaning it with Windex) with only a couple small scratches along the edge. Yet the disc would freeze right after the studio logo. In recent days, discs I receive from NetFlix have truly gone down the hill; I receive discs that are badly scratched and sometimes cracked. What do people do with their rentals anyway?
