Wondering how much bandwith a receiver needs in order to pass an HDTV signal without any degradation? Also, while we're at it, what's the necessary bandwith for DVD signal? I would assume that DVD is a lower number... Friend looking to buy HK8000, which claims HDTV component video switching capability. I want to check and see if it can do it well. Different question, but does anybody know the HK's bandwith? Thanks.
