I don't agree.  The is this possible thread has over e hundred emails in it about several different subjects. It is useless to search on in the future. Breaking it apart into coherent conversations makes sense.

And on topic, I agree that the issue with that old article is clearly that it is describing behavior of the scaler and quantization of the signals coming out of the 64 and cannot be relied on to describe the behavior of different revisions.

Twitterizing a mailing list doesn't help with signal to noise ratio either IMHO

Well i tried to reduce noise in another thread :-D

Sadly i'm not good at magic so the noise just turned up somewhere else :-/

While you certainly added noise, I believe you forgot to add any signal to those reposted messages, didn't you?

This makes irregularities in the video signal more visible, which is especially worse if the plasma TV has a much larger screen size.
