i read somewhere (cdrlabs) that the recording time for 24x recording for a full 700mb of data is 4:20secs and that includes leadin and leadout times. But when i purchased the burner and burned at 24x speed, i only got 5mins6secs tops recording speed every time with 700mb of data. I have dma enabled and used the included 24x speed-rated media that came with the system and also fuji 24x speed-rated medias. Does anyone know what could be the problem? very puzzled!?!
