I just ordered my new HK520. Have not received yet, but had a few questions. For video switching to work, you just hook up video from Dish (S video) and DVD video (Component) through the receiver? Also, I've heard picture quality is better for DVD if run straight to TV. Could it be that much? I think I'd rather have the convenience of one button switching. Can't really video switch my VCR since it's just running through the coax cable coming from Dish to TV cable input? Right??? Not set to a "video" input.
