Thanks a ton, Don. (just got back from the Xmas trip to relatives).
I'll check out the DVR menu again, as well as the Sharp's menu.
Just got the cable brand ne from monoprice.com but it could be faulty. Bad thing is I have no other way to check it; this is my only HDMI set up.

10 minutes later.
Don, you were correct. However it was the Sharp TV that had the INPUT set to skip inputs #4, 5 & 6. I had connected the HDMI to input #4.
This skipping is odd because I know I never did it. I just randomly selected Inputs 1, 2 and 3 whenI first got the TV last year. No one else touches the TV.My wife never watches it as she has 2 of her own.

In any case, among the 7, 397 menu options on the TV I found the "INPUT Skip" selection.
Picture is nicer, better, more color saturated (slightly on the Hoolywood side of natural; gotta fix that.) with the HDMI cable. Sound thru the TV's speakers sucks. I'll leave the sound going thru my bookshelf speakers.
Thanks again!
Jeff
