I'm thinking about picking up an Svideo source selector from RadioShack for when I get Bell Express Vu. My A/V receiver only has three s/video inputs, SAT, VCR, DVD, and all three are currently being used. I could hook up the 3100 directly yo my TV, but my Video 2 in doesn't have svideo and I would like to stay away from composite. Question, with an Svideo selector, how much, (if any) picture degradation would I see? Normally the difference would be so minute I wouldn't care (like right now). I'm just worried that if I add in a second break I will start to notice degradation because of it. Here's how it will go: TV to A/V receiver, A/V receiver to selector, selector to 508 & 3100.
