I am currently shopping for a home theater setup. I have my eye on either a Panasonic or Pioneer 42" or 50" plasma tv. I am also looking at a Denon or Pioneer DVD plaver. From what I have been reading the last several months, HDMI and its predecessor DVI is the way to get a cleaner picture with digital video (DVI only) as well as digital sound both with HDMI. The names mentioned all come with DVI/HDMI. Since the tv will be mounted on the wall and all connections will be run thru the wall, I don't want to run dozens of cables thru the wall. This appears to be a benifit with HDMI, JUST 1 cable to receiver from tv. My question is this: Is it necessary to have a pre/pro or a dedicated home theater receiver with DVI/HDMI connections in order to make use using the DVI/HDMI connections on the tv and dvd player?
