When I play DVD movie in Power DVD 5 Application. The Sound on the movie is not clear. It breaks and its really frustrating. I changed the DVD ROM. Sound Card but its still the same. It works perfectly fine on other system with same Power DVD 5.0. At first I thought taht It could be a DMA issue so I enabled the DMA in both CD ROM but its still not working. The Operating System is Windows 2000 Pro Sp 4. Any Idea.
