If it doesn't work, I'll try the Vision Quest DVD recorder with it's component inputs and the STB set for 480i WS out to the Pioneer 640 and see if that works.
Wish me luck!
Can't seem to get anything from the outputs. Going to do some searching and ask Curtis/RCA if there is a way to make the outputs active. There is nothing in the manual and nothing in the TV menu. Anyone else have one of these and is able to make the AV outputs work?
