problems importing from singer's disk

[songpony]

I've had numerous - and inconsistent - problems importing from singers' disks. I've had audio drops which then cause the graphics and audio to be a couple of seconds out of sync, I've had the graphics completely freeze up for the entire duration of the read and import (which can be up to 90 seconds now!) while the audio keeps going merrily on its way, and I've had the white window of death pop up ("we're sorry, but Hoster has encountered a problem and needs to close now"). It's to the point where I'm extremely nervous about loading a singer's disk except when I'm singing, because I hate to run the risk of having it mess up during a customer's song - however, only loading one song per rotation rarely works, so this isn't a solution. Sometimes the import works just fine, but there's absolutely no predictability as to when it won't work. I can even load 2 songs off the same disk and one will work fine and the other will experience one of the above problems. I have a Plextor Premium drive, which should be one of the better ones, 1 gig of memory, fast processor, and no issues with anything else. Any ideas that will reduce (preferably ELIMINATE) the problems I'm having on import? Thanks!
