I recently backed up San Andreas and decided to test it before i put it away. After playing for about 10 minutes, I noticed the graphics are very choppy if i'm traveling in a car at high speeds. It seems like some kind of a bad draw distance problem that doesn't happen with the original. Occasionally I even get an error message that says "Error reading from San Andreas." I burned the game on Ritek g04's with RecordNow MAX with no errors. I've never had this problem before with any other backed up games. Is it my ps2 laser? Maybe a bad dvd?
