    My DirecTV shows are all recording in 720p even when the show is broadcast in 1080i. I have the video setting showing Native - On & Screen Format - Original Format. I can switch to 1080i by using the format button, but that is a pain. My TV is a 2009 HD Vizio. My DirecTV box is 24-100

    What am I doing wrong?

    First of all I should correct my post. All 1080i shows on all channels record in the 1080i format. It's just that when I want to watch them the default setting is 720p. When I switch the format to 1080i, everything is ok. Why aren't they in 1080i when I press "PLAY"?

    Thanks

    Go into the setup on your DVR and remove all resulation settings except 1080i. Then everything will only display in 1080i.

    Something here is off.
    Native on with all resolutions selected in the setup menu, means you can't change resolution. You only cycle through the format options.
    With native off, then you cycle through all formats AND resolutions, which sounds like what you're doing. This means the receiver doesn't change resolutions unless you do.
    What is the native resolution of your Vizio? Mine isn't a 1080, as the panel is 1366 x 768, so I don't use native and leave the output fix on 720p.

    I would only do this if the TV's native resolution was 1080. If it were less, then there will be unnecessary scaling in both the receiver and the TV. Some HD is 720p, so these would get scaled up to 1080, then back down to 720p if that's all the TV can support.

    Perhaps it isn't obvious, but any TV that isn't x720 is neither 720p nor 1080i native. Which works better for a particular TV is not necessarily the one that comes closer to the panel resolution.

    Perhaps what isn't obvious, is this has more to do with the TV's scaler, and the viewer's perception of the PQ.

    I don't believe this is correct. If you go to the info banner to the Audio/Video tab, you can change resolution even if you use native.

    John, do you know what the software version that you're running is?

    I was referring to the format button on the RC remote. You can press and hold to turn native off, but with it on, each press is cycling the format, but not resolutions, as it does when native is off.

    I did check the tab options [never used them before] and you are correct.

    That is indeed the underlying reason.

    There are very few true 720 line TVs out there and most of them aren't made anymore.

    I don't remember the exact year of my Visio, but it was close to the 2009 of the OP's, which was why I brought it up.

    What about my Hitachi HD CRTs?

    Not sure what you are asking but my Sony CRT can display 480I, 480P, and 1080I.

    720P is downscaled to 480P. So I have H25 set to send 480P or 1080I to my set. Sd's are displayed at 480P and all HD's in 1080I.

    BTW, many of you complain that Sd is terrible. I don't see any problem with SD, so I imagine that it's because it's being upscaled to 480P by the box and displayed as 480P by the TV. The same as it does with standard DVD's upscaled to 480P by my blueray or progressive DVD players. Not as good as 1080I but better than 480I. The newer sets probably have to reconvert again to their native formats.

    I doubt it's "the p" change, and very much bet it's the size & resolution of the viewing screen.
    While SD "isn't bad" here on my 46" 1080p display, the actual image has been multiplied EIGHT to NINE TIMES to fit. This means there is almost 10x the "made up" information to "real" information in the image.

    They aren't x720 (or 750 something including safe area), so they aren't native 720p either.

    Much is made of the importance of being native but the fact of the matter is that many TVs aren't but still produce a good image.

    CRTs have some wonderful properties but if you're watching something other than SD content (especially the 320x240 or less kind that comes from most satellite or cable operators), it probably isn't as distortion-free as a display with a matrixed (plasma, DLP or LCD) display.

    Thank god I've never had a supplier offer so little for SD. I guess your mileage does vary. :lol:

    I would think that since my 51inch Sony CRT (9 years old), and the resolutions I'm viewing are either 480P or 1080I, and unlike the new sets that only have one resolution, this set actually displays whatever resolution the box or Blueray/DVD player sends to it, with the exception of 720P. So wouldn't that be all real information? And as you know, the difference between 480I and 480P is the same difference that you have between 1080I and 1080P. In 480P, the lines are all displayed at one time as opposed to top half first and bottom half 2nd with 480I.

    So wouldn't those two factors, real information and progressive, have a lot to do with my SD not being as bad on my set as those TV's such as those that only display 720P or 1080P?

    BTW My set does not display 1080P, so I set my blueray player to downscale to 1080I, so I assume that my HD is not as good as 1080P. However, I do notice that SD and HD are better with D* than they were with Time Warner.

    "I" stands for interlaced, so it isn't the top/bottom, but every even and odd horizontal line.
    With 1080i, there are way more lines, and "dots" in each line than any SD program contains. If the image/signal isn't scaled up ["dots"/lines added from averaging] your 51" would be showing the program in a thumbnail. The added dots/lines are the "made up" parts, as they're not in the original program/signal.
    Which component does this depends on your settings. The TV may be or the receiver/blu-ray player is.
    I & P in the old analog days, were more noticeable than today with digital, because the digital conversion is basically undetectable.

    VeryOldSchool, Yes I understand the difference between interlaced and progressive. What you say about even and horizontal lines is pretty much what I meant to say when I say top and bottom lines. The D*/cable boxes do a much better job of upscaling to 480P and 1080I than my set does. It displays it at the resolution it receives it. SD from D*, on my set is not bad at all.
