I just returned from visiting my parents in Shaler twp., they have had fios since the end of September.
They switched from comcast after their special rate expired and they are now paying a lot less for phone/internet/tv.
When I walk into the house I immediately notice the picture on the TV looks awful. I look at the connections and everything looks fine, but then I realize they left the TV set on the RF "channel 3" input.

My dad is 76, and doesn't see well, he still can't tell the difference between HD and SD.
Then I checked the other TV in the bedroom, this TV was set to composite video, and the component cables I purchased (from Monoprice) for the TV wasn't even hooked up.

(In their defense my mom said they had trouble setting up the internet, and I guess they rushed through the TV setup)...so be aware, ask questions, and know the difference between HD and SD.
