My SM DVD keeps freezing at the Title screen. It has been resurfaced twice and it worked in the PS2 at the game store. The DVD worked fine for the first 3 or so weeks I've had it but just recently it has been giving me problems. Should I try to get a replacement or is it something with my PS2 that's screwed up. I have a SCPH-39001. Like I said, it was working fine for awhile, now something's screwed. Any help would be appreciated.
