Here's a question from a cheapskate: Is it feasible to use plain old RCA y-cables instead of an expensive video switch? I use a Y cable now to get two digital inputs into my sound system. One input is from Time Warner box, the other from a DVD player. As long as only one source is powered on at a time, everything works fine. I can switch between the two by using the remote control power on/power off. When both of them are turned on and delivering signals, then the receiver gets confused. But other than that it works fine for me. I've thought about the same for component video but am worried about the risk of harming my TV. This would use a Y cable for each pair of inputs. Again, only one source can be powered on at a time for this to work. I'm wondering if there any risk in harming the monitor with this (if I accidentally have two video sources powered on).
