Other than a CD being Scratched (which i checked) what could case my dvd play back to stutter around from time to time in a middle of a movie? oO figgured it had to be a read ahead thing but i dunno, i have a 24x speed drive. maybe its starting to die?

I had an old Sony drive that did that when it was overheating.

hmm it is a rather old drive, its a Hitach GD 2000 off the old ibm i used to use

When you start to get skipping, eject the disc. My one was pretty fooking hot. To the point I got blisters from it.

Or the dma can be disabled and instead you get pio4. Check in device manager (in ide controllers) and see what you have. Tell me if you need instructions on how to reset it.

heh, forgot which ide channel put my dvd drive in whats the differance between dma and pio

The difference is in the speed. Look below.
