PQ=Picture Quality.

I just read the thread on Tivocommunity.com regarding this issue. Very Interesting.

I can't personally comment on this problem as I only have off air TV at the moment and video quality fluctuates when the wind blows. Also, this is my first Tivo, so I can't really compare.

However, I just installed two tivo's in a home that are modulated over the house cable. We are currently having significant image quality problems. We thought it was a bug in our design, but this sheds new light on the matter.

Thanks for the heads up and if I were you, I'd wait a little while longer.
