Hey! I recently started playing the MGS series, and love it. I've just finished mgs1 which i downloaded from ps3store. So now i have started on the MGS hd collection. I played MGS2 with no problems at all for 2 days. Suddenly when I started the game for the 3rd time, it came stuttering sounds I had no idea why i got that, because i have no problems running other games and the sound on them is fine too! I  tried to check out the music on the ps3 too, and no stuttering sound at all. Even in the menu on the HD collection it come weird stuttering sounds Plz, someone help me! This series is the s***!

Yeah I have this too but I get no sound at all!, the disk is pretty much new with no scratches plus it has never done this before however I have just done the latest update, could that be the problem?
