I have recently played with dscaler video enhancer for pc. It's a pretty cool opensource line doubler. It enhances the quality and the resolution of the video input immensly. Nifty calibration features too. Aspect ratio settings also with a bit of tweaking I figured out how to take a letterbox movie and convert into a 4:3 ratio real-time. This is an awsome program for projection panels.
Requires a fairly fast computer 500mhz and a tv tuner card. Take a look at www.dscaler.com
