I will post something or send you a pm as soon as I can. Note however, that I did not see large-scale macroblocking anywhere on A&E. When there was blocking, it was much smaller blocks throughout the image. I don't think you would notice it with moving video.

Have you noticed any improvements in the Comcast picture quality?
I've spent most of my free time this week watching college basketball, Nationals games, and Capitals games, so I have not watched any of the channels in question. I did record a number of different programs late last week, and I downloaded those on Monday and Tuesday, but I have not yet compared them, save for one program on HGTV (see below).
These comparisons are very time consuming. First, the recordings download at just 1.3-1.5MB/s. The recordings are off by a second or two (depending on when the TiVo started to record), so I can't just jump to a specific timecode. I have to find the same frame on both recordings; it is very tedious because I can frame skip forward, but not backward in MPC, so if I move ahead too far, I have to start over. I tried finding the frame in VideoRedo (very easy) and then skipping to that timecode in MPC, but that doesn't work; apparently VideoRedo and MPC keep track of timecodes differently.

But, very simply, what Comcast transmitted last night WAS NOT HIGH DEFINITION
. Not even close. I wouldn't even call it "HD Lite." I think it would be best described as "Widescreen Digital Cable." And I presume everyone is aware of how generally awful the 12:1 compressed digital cable service picture quality looks like.
Based on your comments, I recorded several programs from HGTV. Last night, I briefly looked at Over Your Head: Artistic Bathroom.
The recordings from both providers were horrific during motion. Perhaps the FiOS feed was slightly
less horrific on some motion, but most of the time, they looked equally bad to me. I can't speak to issues on other HGTV programs, but at least on this series, you cannot blame Comcast. It looks to be a production / source issue.
