    I just installed my Pioneer Elite to my 622.
    I'm not sure how to set the signal for HD TV and for SD.
    When should it be set to 720p or 1080i?
    Should it be set to 480i or 480p for SD?
    What signal do the stations send programming?
    Any help would be appreciated.

    Two Ways:

    1) Set it to you tv's resolution and leave it all the time

    2) Hit Menu-6-8 to change resolution for the channel you are on.

    I personally change to 720p/1080i when on HD and 480i on SD as letting the box send 720p/1080i on SD to my tv makes the PQ worse.

    Set it to whatever looks the best to you on your TV. Mine never gets changed from 1080i, but that's just me.

    Here is what is going to work best for the 622 for most people:

    Check the specifications for your TV and find the "native resolution". (In some cases, this might be simply called "Pixels".)

    If that native resolution has the number "1080" in it, then set the 622 (Menu-6-8) to 1080i.

    If the native resolution has the number "720" OR "768" in it, then set the 622 to 720p.

    NOTE: The TV's native resolution is NOT the same as what resolution's it will accept or display.

    I hate the fact it's one or the other. it makes all the SD channels at 1080i creating a lot of artifacting and all the 720P channels studder at 1080i. My friends have cox cable and their HD-DVR has 4 settings it switches to depending on the channel 480i/480p/720p/1080i

    I see the same things you do which is why I menu-6-8 once I settle on a show, plus I watch alot of OTA which is either true 720 or 1080 so I change the 622. People seem to think just leaving it is fine, but I think thats because most do not want to take the time to change it. If it was so unimportant it would not be the most requested feature via polls.

    You know, I disagree with this on several points:

    1. many displays do a better job scaling DOWN than they do at scaling UP. So you may be better driving a 1366x768 display with 1080i signal if sharpness of picture is what you are after.

    2. IMHO progressive scan @ 60 Hz trumps display resolution if it's present in the source, so of course if you have a progressive-scan 60 Hz display, then you will be better off with 720p from the 622 in the event you are watching a program that has 60 Hz frame rate.


    right now, you're forced either to endure a major compromise on at least some channels, or endure a big PITA to swap modes manually through the menus when you change channels.
