Have u heard of MATRIX dvd-rs? Some guy on ownz had a post for them from miterline and said they war said to be good for backing up ps2 and xbox games and there only 62$ for a 100 pk 4x speed. If nothing else they would prob work for moives. :)

But wonder if there is a way to burn 2x media at 4x and if by flashing would that screw up the burner ?

diff write strategies for 1x-2x then 4x
u aint ever going to burn 4x to a 2x disk,not from were i sitting anyway
