What the hell? People actually do their own DivX/XviD backups? I'm seriously shocked over that. I thought people only downloaded stuff in that format. Anyways...
Considering almost everyone in this thread is from either the PS2 or XBox Forum, surely you have access to DVD Burners?
I'm sorry, I really dont see the point in backing up with either of these formats
SVCD and more importantly DVD all the way
Also...
DivX/XviD makes Baby Jesus Cry.
