Has anyone ever figured out how to get the TV output from any video card to work with a widescreen TV? When I put the TV in widescreen mode it looks just like when watching a normal TV show in widescreen. ie. everything is stretched horizontally. I would think that some video cards would support widescreen output as widescreen TVs are becoming more and more prevelant.
BTW, I have a Radeon 8500 running under Panther, but I could do with a new video card anyway so any information would be helpful.

Are you using the DVI output from the video card? Do you have DVI input on your widescreen TV? If you have a DVI input (most new widescreen TVs do) then hook that up and give it a try. Whatever you do, don't try to get widescreen output from a VGA or s-video output - I believe neither supports widescreen.
By the way, be very careful displaying a computer screen on a widescreen rear-projection TV, you can get burn-in since some of the computer screen elements (such as the menu bar) do not channge in color or position.

Actually my widescreen TV only has component, composite and svideo. I realize that these inputs are all 720x480 whether widescreen or not, it is the pixel aspect ratio that determines whether the signal is widescreen or not. Basically what I want is a way to set the TV out (svideo) on the Radeon 8500 to 720x480 (or 640x480) if need be but with a 1.2 pixel aspect ratio. So basically it would be outputting a standard (not widescreen) image that is compressed horizontally so that my TV would stretch the image to proper proportions when in widescreen mode. Basically when watching normal TV I can watch it standard (with bars at both sides) or stretched (when everyone looks fat)
I know many video cards can do things like this with the VGA output as I can select 1600x1024 and send it to my monitor (not widescreen) and everything looks thinner and taller than it should. What I want is the same thing, only through the TV out. I realize that I could pre stretch the video with QT but then I would have to render each movie which would take forever.
Anyone with experience working with widescreen TV and Mac video cards? Any ideas?
