HD channel picture is clear, but regular digital picture scramble
o.k. check all your connections
if you have a newer house check to see if you have a main hub in a
closet somewhere and check all connections. Check your hd receiver and
you may be able to chage the DPI the receiver receives in.
I have this problem on some of my non HD channels, also. So much for going digital. I get fuzz and pixel problems "from time to time", but, if it is really bad and consistent your should call your service provider.
Things to ask also ? are you using cable or satellite.
If satellite T.V. there are other reasons you could be experiencing problems.
hope this helps!
