Hoping someone can help me with this

I've got a dvd which changes scenes quite often, and it works fine on dvd players (there are no scratches or marks on the disc).

However, when i try to play it on my laptop using powerdvd it stalls on one of the scene changes, about 10 minutes into the dvd. Also my harddrive seems to be showing lots of activity. I've tried running it in windows media player but thats even worse, at the menu screen the audio makes horrible blip/squeak sounds.

Is there anything i can do to sort this out? Here are my specs incase that helps...

Laptop
XP Home
2.66ghz pentium 4
512mb ram
40gb harddrive (about 4.5gb free)
GeForce FX Go5200

Any help much appreciated!
