My question while reading this was, "so what about the comparison to DirecTV?" Am I alone in thinking that the Comcast/DirecTV HDTV channel penis size commercials are really getting old...? At any rate, compression is nothing new, but if it affects PQ as badly as those shots suggest, it's yet another "feather" to add to Comcast's cap.

"A thread at AV Science Forum updated last Monday details what appears to be compression of up to 38%, allowing Comcast to deliver more HDTV channels per line while using the same amount of bandwidth."
