Need an upscaling program

[Modular]

What program do you guys use to upscale DVD's to HD output. I have an HD4850 and if there is any proprietary Ati or nVidia software that would do the trick, I wouldn't mind using it. As it stands, I have the nVidia Purevideo decoder, but there are no HD or upscaling settings included with it.

Thanks for the help!

All DVD playback software on the PC does upscaling - and the major players all do a pretty good job of it.
