    Hi all,

    I'm new to the forum and am just getting into HT. I

    have seen a lot of discussion which says that the

    Pioneer Elite RPTVs have one of the best internal

    line doublers and stretch modes. Since I plan on

    watching a lot of 4:3 for now, I was headed towards

    buying one of these sets.

    Then, I started to wonder if there was a "box" available which could perform the stretching and line doubling

    functions that the internal Pioneer processor does. If

    so, then I thought it might be possible to buy another

    TV which has good HDTV performance (but crappy 4:3

    processing) and use this external processor to convert

    my 4:3 content. I know there are processors which will

    line double but I couldn't figure out if they also

    stretch?

    So, is such a thing available? I'd appreciate any

    URLs with info.

    Thanks,

    Dan

    Dan,

    Depends on exactly what you mean by stretching. If you mean just fill the image widescreen by distorting it- most scalers could do this-- actually all RPTV should be able to do it as their "full" mode-- they don't know if they're getting 4:3 dvd or anamorphic-- it's 720x480 to them.

    If you're looking for a slightly cropped/slightly zoomed setting- there might be the ability to do so in outboard scalers with custom settings. I would imagine the Crystal Image scaler offers something like that.

    Also, HTPC might be an option. Using a HTPC and scaling software, you could scale/crop down to the pixel- however you want.

    But if all you want is 4:3 to fill screen width wise without cropping... i would dowbt that the difference between RPTV sets would be all that great as they all have to have this mode for Anamorphic DVD-- so I would imagine it looks acceptible on most sets.

    But if you're looking for more complex crop/stretch combinations-- custom scalers like Crystal Image or HTPC might be better for you.

    Thanks for the reply Vince.
    It turns out that I do, in fact, want to do more than
    just fill the screen with the 4:3. I agree that this
    function seems to be available on all RPTVs (and, IMHO,
    looks equally screwy on all of them [​IMG] ). As I mentioned,
    one of the strengths of the Pioneer Elite sets is that
    they have some extra partially stretched, partially cropped,
    modes which look more watchable to me. It seems to me there
    are several good RPTVs out there which look great but
    don't have these "in-between" modes. These other sets
    are quite a bit less expensive as well. I thought that
    perhaps an external processor would be a good match to
    one of these sets (from a price and feature point of view).
    I will check out your suggested manufacturers.
    Thanks,
    Dan

    On some HDTV sets including a lot of Pioneers, you don't have any aspect ratio control for HDTV or progressive scan source material.
    Buyer beware. You will be cursing sooner or later if you are stuck with this problem, and stretched 4:3. Let's send a message to manufacturers by telling the salesman you are not buying the set because of that problem.

    I also have a Pioneer Elite and watch everything in Natural Wide mode, so I know where you're coming from.
    As far as scalers are concerned, I know that the Rock (from TAW - www.tawforum.com) offers several stretch settings that come close to what you're used to. Supposedly Pioneer stretches things more on the sides than in the center, which I have trouble verifying, and the Rock doesn't, but I doubt that that's significant. The Rock Lite costs $3000, and the more flexible Rock Plus is $6000, I believe. I suspect that the Leeza (from Key Digital) also offers something similar, and maybe the Vigatec scaler, but I'm not certain. The Faroudja NR does not, I'm pretty sure. Of course at these prices those scalers are more appropriate for front projection units.
