I have a Pioneer DVDRW DVDR108 (OEM), and I use Alcohol 120% v18.104.22.1685 and I want to burn at 2x or 2.4x speed because I've heard that it will give less errors when playing the game. It's strange, an hour ago I burnt MGS3 and Prince of Persia at 2.4x, but now I want to burn another but it only gives me the Maximum or 4X as options?? I noticed this before as well, but for some reason it gave me 2.4x for a time so I was glad, but now its back to 4x. I check alcohol-soft's site, and my burner is supported what the hell is going on.... Also I tried DVD Decrypter and CloneDVD, I burnt Jak 3 and some other games (approx. a full 4.6 gb dvd), choosing 2-2.4x but it burnt in about 15 minutes, isn't that really 4x?
