Having been scouring + searching tons of threads tonight I am struggling to work out the difference between 's video upconversion' and 'component video up/down conversion'. Basically I am stuck between the yamaha rx 650 and the dsp 750, but need to be able to input an s video or composite signal from a wi fi receiver (that displays jpeg pics) into the amp and then onto a panasonic pw6 plasma via component board (or rgb scart ). If the 650 can do this I will save a lot of money, but having checked the yammy website and all the postings it does not seem to be clear exactly what the s video 'upconverts' to?? Is it simply a channel through to another s video source or any relevant signal?. I think in my circumstances I would be safe with a dsp 750 but if anyone can help me with this I would appreciate it as I am completely confused now and want to get on with a order before I turn into jabba the hutt !
