i have burnt several games without any coasters, but when i try to run the backup of Shadow Hearts 2, i cannot get past the opening cutscenes. it keeps totally locking up on me. All the dvds i use are Memorex 4x DVD-r's. I tried buring it at 4x and 2.4x, and both locked up. I know it is not the image, cus other ppl have tried it and it worked.
