My THD started to have bad pixelation yesterday and it was driving me crazy. I could not even watch any of my HD channels it was so bad. I went down to the basement and messed around with the wiring and splitters. I then went back to the TV and switched inputs to my HD Receiver (yes I kept it in case I ever wanted to use VOD). I was surprised to see it have the same pixelation issues my THD had. I wonder how many of these problems have nothing at all to do with the THD but only with the cable company. If I had not kept my HD Receiver I would have never known my THD was fine.
