Hey all, I just joined the forum and am similarly just getting into home theater. I'm piecing together a modest system in my basement that I will later take with me to college. In shopping for receivers, I have noticed that many offer video upconversion, either from composite to S-video, or composite and S to component video. My question is: do these receivers actually upgrade the video signal to either S or component video, or do they merely pass the lower-quality signal through the better connection? If the signal is actually upgraded, this would help me as I have 3 video game systems in my current setup and will likely have a 4th when the PS3 is released. Being able to hook all these systems up using whatever type of connection I currently have for them, and then being able to see all of them in component resolution would be great. However, if the signal isn't actually upgraded, I would just look for a receiver that has 3+ component video inputs and get the correct cables for each system. Sorry for making this such a long first post, so thanks to all who stuck with it!
