i own guitar hero 1 and 2, and at completely random times, the song track will freeze, the background keeps moving and the music sometimes plays and skips back. then the music will be behind and it makes it harder to play. some songs have this happen so much, that they are virtually UNPLAYABLE! and i do know that its my ps2's problem and not the disc's because they never freeze at my friends house. is there an expert who has seen this before? someone who can tell me how to get it to stop? please and thank you.
