Welcome to the forum!
Well, I'll get the discussion going, but I'll admit up front that I'm not sure. Basically, I'm just bumping your post to see if anyone who knows can chime in.

The manual for the RX-V2200 doesn't say anything about video resolution, so I started researching if the 60 MHz frequency response of the component video outputs on the RX-V2200 is sufficient. I haven't found any real agreement on that, yet.
One thing, though. It might be the second set of cables that you are using when you route the video through the receiver. Are you using component video cables (or video cables in general)?
