Ok guys, I know there is someone who can assist me. I "almost" purchased an Onkyo 787 on clearance. However, I'm now holding out until I get something cleared up. What is the difference between wideband and regular component inputs and outputs? Will regular component inputs and outputs not support HDTV and progressive scan DVD? I noticed this difference between the Onkyo 787 and 797 and thought I'd better not buy until I got this cleared up. Shouldn't there be one specification for component I/O? If anyone has the exact details on the signalling I'd appreciate it. Thanks.
