isobuster sucks..... do this.... make an image of your CD.. use blindwrite to do this.. www.blindwrite.com... make the image a bin/cue... then goto www.daemon-tools.com and get Daemon Tools.... mount the drive and load the image u made from your CDROM.... it makes a virtual CDROM/DVD drive.. therefore u can get away with not using your CD... its also good for speed concerns if your CDrom is too slow... hope it helps PsY
