    I'll check the Food Network I haven't watched that channel in a while. Any good shows on it?

    They didn't forget it. It is created locally in each market. For some reason, however, some markets have theirs in 1080i MPEG-2, and others in 720 MPEG-4.

    Over here, Food Network is the overcompressed 720p.

    I am in the Philly suburbs and they just started the 720p conversion of premiums, right now only the main HBO and Cinemax have it so far. I am watching The Revenant now and it's very muddy and even pixelated at times on the edges and dark sections of the screen. I recorded it and watched it a few months ago from HBO and was amazed how good it looked on TV after having seen it in the theatre. Now it's shite. Looks like Comcast will be losing another subscriber at some point.

    I just can't imagine watching The Revenant like that! It is an *incredible* movie, and should be watched on UHD-BD with HDR and DTS-HD MA to truly enjoy. It is a feast for the senses, meanwhile a brutal movie to watch. Even relatively good 1080i on cable would look terrible compared to high bitrate HEVC encoded 2160p with HDR.

    It's probably my favorite movie of the past 5 years or so, almost every thing about it is incredible--lighting, sound, acting, music, directing. I am limited by my own tech to just my TiVo or Blu Ray. I was pleasantly surprised how great it looked on 1080i on my 4K Samsung when seeing it a second time after the theatre and dismal watching it last night. Couldn't stand to see more than the first 10 minutes and that was it. I hope more people complain to Comcast about this but sadly Comcast probably doesn't care and half of their customers probably think it looks fine.

    You said you saw it in theaters, so you know what it really looks like, but you haven't seen it at home until you've seen it on UHD-BD with HDR. It is amazing. Comcast doesn't care, most of their customers can't tell the difference, which is also sad, since it's so obvious when you see it. It's a total mess.

    I didn't see it mentioned in this topic but it looks like Comcast flipped the 720p switch in the Taylor/Detroit area. I noticed there were a few incorrect channels in the Tivo guide which was messing up the "press D to watch in HD" option so I was comparing between my X1 and Tivo to get the correct lineup reported. After that I went to watch something on StarzHD and thought it looked off(like a poorly done upconverted DVD) so I pulled up the info to make sure I was actually on the HD channel because I wasn't sure if it was another weird Tivo issue or what. I then noticed the signal was 720p. I started going channel by channel and outside of a few channels(mainly locals) everything HD is showing as 720p.

    Clearly, the market segment that cares about picture and sound quality is a niche to Comcast. Look at what they promote: mobility, voice control, etc.

    I think Comcast believes that the fact that many people watch TV on mobile devices means that people don't care about picture quality. I don't think that's accurate.

    I had a discussion with someone fairly high up at Comcast about the MPEG-4 transition, and part of the answer about how they are doing this and why they are doing it boiled down to something along the lines of focus groups showing that it looks the same to most people. I don't doubt that, as you see a lot of people 15' away form a 55" TV, and some people not even caring about SD vs. HD. It's pathetic the lack of criticality that most people give to their TV veiwing.

    I try not to get angry or generalize, but whoever can't notice is as blind as a bat or has terrible eyes. It's so obvious it's ridiculous. But I guess I shouldn't be surprised, I read on AVS Forum a few years ago that something like half of all people with a big screen HDTV don't have HD cable subscriptions and are watching SD.

    I saw an article today that said Comcast will be deploying their 4K set top soon. I wonder if it will be true 4K or some squashed down version that looks like crap?

    It depends on what you call "true 4K". I can guarantee it won't be 4K Blu-ray quality, but it's possible it might be 4K streaming quality.

    I wouldn't put it past Comcast to degrade picture quality for all non-4K channels and then charge a hefty premium for 4K.

    It sounds like they already did with the 1080i to 720p fiasco, in preparation for this 4K eventuality.

    Chicago area, yes, everything as far as I can tell compressed other than local channels. Guess they won't do that only because can get those uncompressed with an antenna, for FREE if you are lucky enough to have reception in your area. ESPN and Comcast SportsNet used to be about 7-9GB per hour recorded. Now about 2GB per hour of recording I think. Charging more and more (now by increasing/adding fees and rentals so they can hit those who took contracts, fees/rental not included in "price guarantee") and getting less and less, that's the Comcast way.

    For fun I just recorded 15 mins ESPN SD and HD, Comcast SN SD and HD, all same time slot.

    ESPN HD 15 mins .43GB, about 1.72GB per hour.
    ESPN SD 15 mins .46GB MORE than HD, 1.84GB per hour.
    Comcast SN HD 15 mins .54GB, 2.16GB per hour.
    Comcast SN SD 15 mins .31GB, 1.24GB per hour.

    From what I see all HD other than locals channels is 1.x to about 2GB per hour. Well, more room on the hard drive is about the only "plus" I can see. Hey Trump, disband Comcast, even though some people might lose out on something that is one company I would not mind seeing go under.

    People don't seem to notice anything. It's obvious to me on my 4k TV, although I'll admit I had a hard time telling on my parents' 1080p TVs, so you definitely need a good display to tell the difference. Also, a lot of people have too small of a TV and sit too far away from it. Comcast, however, is going against the trend, which is bigger TVs and more 4k TVs.

    They want to do locals, but they need high bitrate fiber feeds and a localized encoding infrastructure to be able to do it. Right now, their MPEG-4 encoding is centralized nationally and distributed via IP over their national fiber network to headends that modulate onto QAM.

    How do the non premiums look compressed, like ESPN or any cable news channels, are they noticeably worse?
