    I recently upgraded to the HR20-700. Missing DLB, but I digress.

    I have my unit set to native resolution. Sometimes when switching between 720p and 1080i the screen goes black. This happens with recordings as well as live TV.

    This is a semi-frequent nuisance. Does anyone have insight into a software patch that will fix this issue and when it might be released?

    Yeah it will do that every time you switch resolution.

    Have you tried turning off native mode?

    No...I thought I might lose some PQ with that option. Will ESPN lose its quality if the receiver is set to 1080i?

    I prefer the HR20's scaling to my TV's, but I too digress. What model TV do you have?

    When the HR20 is adjusting, you will typically see a light gray screen. The "black" is probably while your TV is adjusting to the new resolution. It is just something that will take a finite amount of time. For me, the increase in PQ is well worth the wait, as I am not much of a "flipper". I do like to "surf", I just do most of it from the guide.

    Whether or not Native=On, with various resolutions selected will be better or not is completely dependent on your HDTV, and on your own personal tastes.

    For some, particularly those that like to "flip" channels a lot, a single resolution seems to be better. For others, the increased PQ, and the ability to use your TV's formating options for SD material, outweigh the lag in channel changes. I guess that is why native mode is an option.

    This is a function of your TV... not the HR20. I have several HR20's and various HDTV's... some will do the blank screen when resolution changes and others don't.

    If you want to eliminate it just turn native off and set 1080i, or whatever is your highest native resolution. This may not give the absolute best picture, but it's pretty darn close. This will eliminate the resync problem on the TV and speed up channel changes quite a bit.

    Speed things up even more by turning off all the animations, etc. on the HR20.

    If you do the above it's almost tolerable.

    here's a question for you. I have a Samsung HLP-5063W. It accepts a 1080i input, but it only displays at 1280x720 or 720p. If I want to turn off Native, would I get a better picture setting it to 1080i or 720p?

    The wife is telling me it changes channels too slow :p

    Just try both and see which looks best to you. Since DirecTV favors 1080i that would be my choice if they both look the same to you.

    In Setting / Display / Preferences turn off Scrolling Effects... that will help speed things up too.

    You won't turn this dog into a Ferarri, but these things help a little.

    kitchj,
    it's really a matter of personal preference. I leave native off, but keep my resolution coming from the HR-20 at 720p. I do this because my TV is 1080p (Samsung as well), and I don't see a huge difference either way, so I stay in a progressive mode all along the way of the signal. Works for me, but it's personal preference. Sounds like your TV may have to do a lot of scaling if you use 1080i, so if you have native OFF, you might try 720p as your output from the Hr-20 and see how that works for you.

    Thanks guys. I guess I'll just play with it. I'm thinkin I probably will end up stickin with the 720p so it's progressive, but we'll see.

    I've been a native on guy feeling that my TV's would be much better upscalers. However, I have recently been experimenting with native off displaying only 720p or 1080i in order to improve channel switching time. And you know what, I really don't see any difference. Don't forget that if you have a 1080p TV, then no matter what you do the TV has to grab it and bring it over the last hurdle. I've decided to leave native off and benefit from the quicker channel change times.

    I have stuck with native on and only 1080i selected. It seems to be the best choice for me.

    What is the difference between Native Off and only having one resolution selected with Native On?

    It is essentially the same as having selected a fixed 1080i as you have already guessed.

    What it comes down to is how your TV looks to you and that is something that none of us are qualified to do.

    None that I can tell. When you deselect a resolution it defeats the Native On setting for that resolution. If you only have one resolution selected then the Native On setting has no value.

    IMHO, you will want to turn native on. I have the KDS-55A2000 (a step down from yours though from what my "electronics mentor" tells me the scaler is the same) and I prefer having the TV do the scaling. I also have the box output in stretch and then have the TV do the scrunching on 4:3. If I have the box output with pillars, I get a white line down the left side of the image.

    bottom line, it's your preference.
