I'm still trying to recover disk 1 of Harry Potter, it plays the 1st hour OK, but the last 15mins are a bit of jumble, blocks appear, occasionally freezes etc.

On my standalone Phillips player, and I can watch the majority of the last 15mins, but it won't play at all past the 1st hour on PowerDVD in me PC.

I've tried importing the DAT file into VirtualDub, but it gets to where the problems start on the film and then no further. Should I just give up on this disc, or is there any way to recover some of the information ?
