I have an NEC ND-3550A DVD burner. The problem I am having is when I play a commercial movie DVD I get a picture but no sound. If I play a music CD on that same burner I get sound as normal so I know that the cables are connected correctly. Does anyone have any thoughts to what I could to to enable sound when playing DVD movies?
Note: This is a new system that I built. It is an Intel E8400 CPU on an Asus P5K-E motherboard. The OS is Vista Home Premium 64 bit. All seems to be working well on this system except for the problem that I just described.
