is there video card for upconverting dvd playback

I have a little clarification for you but I don't know the specific answer to your question.

There is no way to truly upconvert a standard DVD to high definition. The only function upconverting performs is upconverting the output from standard DVD format of 480p to a more friendly native resolution for high definition televisions of 720p and 1080i. If you have a newer fixed pixel display then your TV already converts everything to it's native resolution anyway.

So in summary, all the upconverting DVD players on the market are mostly a gimmick and the salesmen will try and tell you they are necessary if you own an HD TV. In reality, conversion has to take place on fixed pixel displays anyways and most people think the converter in the television is usually the best.

The only way for you to get an HD picture to your TV is to have an HD source like HD DVD or Blu Ray.

Upconverting DVD players aren't quite a gimmick. When you play back a DVD on a high-def TV (or computer monitor), upconversion always has to happen somewhere. The problem is that your typical HDTV does a really poor job of it. So upconverting with a DVD player (or better yet, with a computer) does provide an increase in quality over what you would see otherwise. Keep in mind that the goal isn't to reach HD quality, just to upconvert without losing quality. I play back DVDs on a Sony 720p TV and they look amazing, at least as good as a high-end DVD player.

Upconversion on the computer happens automatically when you play back a DVD in full screen on the TV (assuming the TV is set at the correct resolution).

Thanks for all the help guys --- makes complete sense --- glad I am using computer for all my playback stuff
