WGN 9 "The CW" in Chicago is airing it in HD @ 14 Mbit 1080i.
The quality is pretty awful. No fine grain at all. It looks like it's been scrubbed of all fine detail. I don't remember Two and a Half Men on this channel looking this bad; in fact I thought the quality of those airings was starting to approach Blu-ray quality.
Have they DNR'd the new syndicated versions?
This looks to be beyond typical bitrate-starved MPEG-2 artifacts... as if it's a problem with the source.
