    Since some 4:3 TVs can do the vertical squeeze, is it possible for a 16:9 set to do a horizontal squeeze to watch shows or DVDs that have a 1.33 OAR? I've never heard of this on a widescreen set, but it seems like it could reduce the burn-in potential of having those gray bars on the sides. Is this technically possible? It would eliminate one of the concerns of buying a widescreen at this time if you still watch a lot of broadcast TV or have a lot of 1.33 AR DVDs.

    Maybe you mean expand and not squeeze on the widescreen? My Toshiba 65HX81 has 5 modes for viewing: standard 4:3 with gray bars on the sides, three stretch/zoom modes to 16:9 which show partial pictures, and full stretch and zoom to 16:9, which is also handy for watching DVDs and widescreen content.

    There are some 16:9 TV's that don't have 4:3 mode during progressive scan or HDTV, I suggest you stay away from them. Otherwise you will be cursing sooner or later.
    In the horizontal direction it doesn't matter whether the electron beams scan the entire screen width or just the 4:3 area so long as the resolution during 4:3 mode is adequate and there are no problems with convergence or geometry.. Bring your AVIA test disk (Video Essentials doesn't go high enough) and play the 200 TVL resolution pattern. You should see resolution all the way to 540 TVL.
    With black bars screen wear would be more uneven leading to more screen burn effects, compared with gray bars.

    The 16:9 squeeze on 4:3 sets is totally different from what you want.

    Basically you want to watch a 4:3 show on a 16:9 set, but you want it to either

    a-Fill the screen

    or

    b-not have grey bars.

    a- You can either stretch the image, or have the TV only scan the 16:9 middle area of the image. Toshiba's do a fantastic job on the stretch from what i hear

    or

    b- There is a way, at least on Toshiba sets to turn the grey bars black. Do a search on it

    or you can use Mattes on your set to block the grey, again search the forum
