i made legal backup copies of games that i own. Sims 2, AOE 3, Star Wars Battlefront. After i burned them in Toast 8, i mount them to see if they work. The work fine and the game runs fine. But after i take them out and put them back in, they dont work. They work fine on my macbook. I noticed that ripping a DVD took a little longer than usual and burning in toast took a little bit longer. Do you think i should get a DVD drive lens cleaner disk? if so, which one would you recomend for a Dual g5 powermac?
