    I do think it is a shame we didn't at least get to see analog HD here. I also think that when they were definind the HD standard for broadcast TV and reassigning frequencies... they could have changed the channel assignments and given more bandwidth per channel. This would mean fewer OTA channels in any given area but I'm not sure there are any areas that have enough OTA channels to make that an issue.

    Today we have 2-13 VHF and 14-80 or so UHF... I know some of that will go away in a couple of years. I believe after Feb 2009 we will be left with 2-50 although I have heard some of the lower VHF may go away as well. In any event, are there any areas with 30 OTA channels? If not, then everyone could have benefitted from having more bandwidth per digital channel with new channel assignments that would kick-in after 2009 when the analog is shut down.

    If they had done that, then we could see another OTA quality increase in a couple of years.

    Thanks for the corrections.. I knew it was either 50 or 51, but couldn't remember at the time. I also knew we didn't go up to 80 UHF anymore, but forgot to edit that part of my post after I saved it.

    It once went from Channel 1 up to channel 83, but the feds have been snipping off frequencies for years. Another snip is coming.

    Fortunately the next snip (to 2-51) also includes a shift in technology that will allow more stations to exist on less frequencies.

    I thought that they were going to cut off channels 2-6 also.

    nope - that idea got canx'd. Although, it is NOT desireable space as far as DTV is concerned.

    The reason they snipped channel 1 was due to too much atmospheric interference. Channel 2 is still bad every once in a while.

    Does that mean ch 58 in Sacramento will have to get a new channel number? They are owned by KCRA channel 3 so they could just move it to a ch 3 sub channel.... actually it's MY 58 so it's HD so I gusss they want to keep it it's own channel....maybe MY 51?

    If they are actually on the air as a LP or CA station on channel 58 they will get a new LD station at transition and be able to remain on the air. The channel number will not need to be changed, regardless of frequency that they will be using. They can remain MY58.

    I have seen a marked difference in sd quality too. But unfortunately I have also seen my hd quality look less than WOW now. I tried to watch the WIckerMan on Cinemax HD the other day and I really didn't see much difference in the pq between the sd and the hd version.

    I think it is a good thing to improve the sd quality especially if You use the Partial zoom mode , but something has changed in the hd quality. There is little difference in the picture to me now. Yes the 622 is set for 1080i using hdmi.

    Maybe I am just so used to the hd picture now that when they improved the sd I can't see much difference or the sd is now as good as the hd quality? Either way I would love to see an upgrade that brings the hd picture back to full HD quality like it was a few years back.

    Yeah, me too... it does seem like the HD quality has gotten, let me say, a bit questionable. At least for some of the national network channels. The VOOM channels still look great, but I looked at some of the standard national channels like HGTV and FOOD, and I couldn't see much difference in quality from SD to HD.

    But all I know is that the Cubs games on WGN and CSNCH look much better now than they did when I first got the 622. Still not HD of course, but they're almost as good as they were on my old 480i set, in terms of clarity. The progressive enhancement makes them better in that sense, but you know what I mean. That is going from a native 480i set to a blown up 1080p set.

    I have the superstations and KTLA definitely looks WORSE than it did a month ago. To compare, I went back to recordings made just a few months ago and compared them with recordings done in the last few days. The compression is horrible and the picture looks much worse. Sometimes I feel like I'm watching a YouTube video.

    I dropped all Superstations that I used to watch over a year ago. When the Denver CW/Wb went from great picture quality to an overcompressed mess, I dropped them. All Superstations , especially the Ktla station looks like crap now. Hopefully when they relaunch the mpeg 4 service this will change.

    Yeah the track & feld recordings I come home to are !unbelievably! bad, even the so-called HD ones on ESPN. Good thing I'm a junkie for the programming and lap it up anyway. :) But good grief. I suspect it's not just Dish that's messing up, it's production values in play. But IMO we're also to blame for sitting back and taking it ... we need to start phoning and writing in. Who wants to invest in all this equipment and end up with a washed-out, macroblocked, bleary mess to show for it?

    I wonder if the reason why the sd looks better on some other sd channels other than the superstations, is because they dropped all of those shopping channels?

    Will SD look better if i set my 622 at 480i, 480p, 720p, or 1080i?

    So far everything that is HD looks better on my Panasonic plasma when it is set to 1080i except for ABC, ESPN, and Fox which look SLIGHTLY better on 720p.

    Does it make any difference what your setting is for SD?

    Does SD look better through component or HDMI?

    And lastly when HD local channels are sending digital SD material are they broadcasting it on 480i or 480p?

    When you get HD locals through DISH are you getting what they originaly broadcast or is it changed somehow or does it come by satellite somehow?

    These questions must really be hard to answer.

    is there anyone who can answer these questions?

    I believe the quality of SD picture you get through your 622 largely depends on your display, not the 622. fixed pixel displays can have problems with the SD display enlarging pixels up to 4X.

    HDMI and component are usually undistinguishable from each other some say HDMI looks better - again it really depends on your display.

    Local channels do not switch output. Regardless of whether the material is HD or SD they stay at either 1080i or 720p.

    Dish takes the feed from the provider and either encodes it mpeg2 or mpeg4 with variable bitrates. They claim they do not alter the horizonal or vertical sweep rates.
