Can anyone explain this in more detail? I understand (to a certain point) that the hardware decoders are better because they don't require resources like the software decoders, but how can you tell if you have software or hardware decoding? Is the hardware decoder built into the DVD drive? The reason I bring this up is because a co-worker burned a constant 8Mb/sec DVD and my client is saying that the video is chocking. She has a DVD with a varible bit rate of 5.5-8Mb/sec video and that has no problems at all. It definitely sounded like she had software decoding because we suggested she disconnect from the network (to free up some resources) and the disc played fine after that. I told my co-worker to stick to around 6Mb/sec for any new DVD's he makes...does that sound fair enough to be compatible with software decoders? Anyways, I was just interested in knowing more about the differences between hardware and software in detail.
