HDTV Question

I just recently picked up a 37" Olevia HDTV. I had a 26" Olevia before this and it didn't have this problem. I'm assuming because the picture is bigger it's more obvious now. What would be the reasoning behind the noisy background? It's not there when I'm playing on my Xbox 360, it's only on HD channels. SD channels are fine, obviously not a good picture, so not nearly as noticable.

I have a Comcast DVR HDTV box with HD turned on. I am getting very frustrated. On demand and HD channels also get blocky and start skipping around... this isn't very often, but enough to be annoying

I am running this with a Philips HDMI cable to the HDTV box
 
My guess would be signal compression for the signal, and that the TV's greater size is showing it. That might explain why the Xbox360 doesn't have this problem.
 
and how would something like that be fixed? I added a 10 db amplifier to the cable which gave a little improvement
 
Well, when I was having a problem with a new 40-in HDTV, I called Comcast. They sent out a tech and we determined that the TV was faulty. I returned it and exchanged it for another, and never had a problem.

Bottom line - call Comcast to check it out.

And . . . the tech also found that they had the wrong splitter installed on their cable. That made things better as well.
 
Have you tried component cables? Are you outputting 720 or 1080 from the comcast box? What's the TV's native res?

no I haven't tried component on the box, that's occupied by my xbox. I did notice on my last tv that the component was a little bit better picture, which would make absolutely no sense at all to me. (my last TV didn't have an HDMI port, just a DVI)

I have tried both 720 and 1080, they both look about the same. The resolution I beleive is 1368?x768
