I use coaxial for the dvd, and optical for the satellite and xbox, so I would love to use the component inputs on the reciver, but when I try it though the receiver, the whole screen is all blue with tiny bits of black outline of the picture. But I've only tried 1080i sources, so maybe it only works with 480p. Which doesn't help me anyway. I looked in the manual and it didn't say anything except which color goes into y pr pb, nothing about which resolutions it could use. Which is stupid, it should work with 1080i sources, right?
