    When my box switches resolutions, the screen goes black, then it takes a couple of seconds to paint on the black, then a couple more seconds for the blue background to paint.

    E.g. Live TV and menu shows in 1080i, settings switches to 720p.

    Rather annoying, when I've gotten used to my FiOS DVR that never needs to switch resolutions or switch of the video feed, e.g. I can search, menu, anything, while the video keeps playing uninterrupted and minimized or in he background.

    The video settings are configured to support all resolutions, my TV supports all the offered resolutions.

    Is there any way to configure the box so it always stays in one resolution, instead of switching?

    Set your output to only one output resolution. Mine is currently set for 1080P60 output. This will avoid those issues.

    Your FiOS DVR was also probably set for one output resolution as well. Since anytime there is a resolution change from any device on HDMI it is going to resync.

    Yes, only select the resolution that most closely matches your TV's native resolution, i.e.- 1080i/p, 720p, etc. Since you selected them all, the TiVo is going to output whatever the channel's active resolution is instead of converting them to what I just told you to set, hence the TV always switching to accommodate the differing resolutions and causing exactly what you're describing.

    EDIT: Doh, beat me to it!

    Yeah, go to Settings &Messages>Settings>Video. Then check the one resolution you want.

    Im using mine for OTA and Amazon VOD, with 720p, 1080i, 1080p and 1080p/24 selected. Resolution changes are fast and Im not having an issue. Sounds like a handshake delay with some device in your chain.

    Thx for the advice.

    I set it to 1080i, and 1080p24 passthrough, matching most of the material I watch, and letting the TV do the scaling.
    I still have a short delay with a black screen between menu and settings, but no resolution switching.

    If you set it to that only, then the TiVo is the one doing the scaling.

    True, for non 1080i content only, but I don't have to deal with the box switching resolutions leading to a poor user experience for me.

    I'm curious, is it better in general (quality of image/video wise) to let TiVo do the processing (e.g. keep on 1080i/default), or the TV adapt to TiVo's output? Or no difference at all?

    It depends on what the choices are -- 720p channels look about the same on my 1080p projector whether scaled by the projector or the TiVo. But they look better if I let my iScan Duo Processor do it.

    Gotcha - so generally doesn't hurt to try to let an external source (e.g. TV or processor) try to upscale etc.

    That being said which options should I go with as far as output options, just 720p or 1080i, or also add 1080p and 1080p/24 as well?

    The fastest channel changing is usually when the TiVo is set to output only the native resolution of your TV, often 1080P these days. If the scaling of 720p and 480i channels looks good, I'd leave it there. Add 1080p/24 only if your TV can handle 24fps.

    Yes, I've noticed my DUO does a better job scaling 720P, but I just leave my Roamio set for 1080P60 output to avoid the resync issues. Besides for me, 90% of my TV watching is from channels that broadcast in 1080i.

    With my situation (VT50) and knowing Broadcoms history, I prefer to send Native as much as possible to my tv. YMMV.

    Is this problem also happening using the Netflix App?

    I have this problem with my Premiere and it drives me nuts. I tried pushing everything up to 1080i and all resolutions below 1080i puts a horrible moving white bar at the top of the screen. Netflix will rescale 20-30 times in a 22 minute episode. If it's not fixed in Roamio, I'm not sure I want to buy it.

    I recently installed a Mini in my bedroom. My TV there only has one HDMI input and I also wanted to keep an Apple TV attached, so I had no choice but to use a component connection for the Mini. Seemed sort of stone age, but to be honest it's working great. Picture quality is faultless (though I admit it's not a big screen), instant switching between resolutions, and Netflix using native 1080p24 had a noticeable cinematic quality. I have the analog audio directly connected to my sound system which allows me to play Pandora with the the TV off (Marvin Gaye channel of course:)).

    I stopped using Netflix on my Premiere and Elite because of the scaling issues, particularly going in and out of 1080p24; so far, on the Roamio, no scaling issues at all and 1080p24 looks great

    Doesn't it blank out for a second or two when the framerate switches to 1080P24? This was why I unchecked 1080P24 in the video output options and just use 1080P60.

    The problem with watching Netflix 1080p24 content at 1080p60 is that you are forcing the Tivo to do a telecine conversion, which sort of defeats the purpose of Netflix using 1080p24 in the first place. I agree if your HDMI connection blacks out that is a serious problem and you really have no choice but to do what your are doing if you want to use the HDMI output. But I would at least try the component output at 1080p24 to see what you think of it. It's somewhat of a matter of taste, but many people (myself included) prefer the film like appearance of 1080p24 versus the noticeably more video like appearance of the same material converted to 1080p60.

    Then why even have an iscan Duo video processor/scaler?
