I assume you could convert the signal to 480p with the framemeister thingy, if it can just insert a black line in between every scan line in the original signal to stretch the image twice vertically. Though that would mean your black lines and scan lines would be of equal width and that may be too much for the eyes.
Sounds good, but if I'm gonna drop a stack of cash on the Framemeister it's getting plugged into my 50" Panny Plasma, not this $20 thing haha.
