I'm trying to sort out the playing of DVDs on my DG35EC motherboard. Whenever I play a DVD the video and audio stutters and is choppy. I'm pretty convinced that it is an issue with the DVD interface because if I copy the data to my hard drive it plays fine. I don't think it's the drive since I've tried a couple of different drives with no change in the symptoms. I've investigated Windows registry settings and note that one of the IDE interfaces is in PIO mode. I've tried resetting it to DMA without success. Is this a known issue with this motherboard? What else should I be looking at. Thanks!
