Hmm I think I see what you are talking about with color shifts. I was all excited to hopefully watch the ABC NBA games in HD on Sunday afternoon, but nada. When it first came on...and the announcers were talking...it was HD..then when it went to the floor....it was all crappy looking with reds and blues...and bam...it immediately went to SD.
I even went to the ABC HD from Baton Rouge (50.4 I believe) and it was doing the same thing. I was very disappointed.
I did try to pick up WVLA or whatever it is, the Baton Rouge NBC with my outdoor antenna at 34.1, and no luck, I couldn't pick anything up. I know Rich had told me it was on 33.1, but their website said 34.1, either way, not a bleep on the radar.
Looks like it will be forever before I get to watch Sat. Night Live in HD.
Oh yeah, this guy who came Saturday to install my new 622 E* with the HD channels told me he was told that our local HDs will be added THIS month. I don't know how accurate he is, but that's what was told to me.
