It was the worst, I had a house full of friends over and I found myself apologizing for the garbage that was being displayed by VT30.
In my house are a Pioneer Elite, + two Panasonic TH-42PW6 EDTVs (Both purchased in 2003)
We ended up watching most of the game on the Elite and some were in one of the rooms with the EDTVs, reason the V30 on any motion displayed square blocks that made it unbearable to watch, I did notice it on the pioneer, a little, but almost unnoticeable. Now, others not as picky as I am, said they didn't see it on the Elite + I saw no blocks on the EDTVs.
My guess was/is the signal being fed from TWC was crap, but my others TVs handled it, also, I think because the VT30 is 65" it acts like a microscope and displays the garbage because of its size.
This set will be returned and I'll wait for a TV that can at least live up to my Pioneer Elite in quality, or try and find a 151 for sale.
