I recently upgraded to a 612 DVR and connected it to my SDTV while waiting for delivery of my new HDTV. I used the component outputs on the receiver and couldn't get a signal (S-video and composite worked fine). I played around with the receiver output settings and the best I could do was come up with a wavy split screen picture (both sides were the same picture). When I hooked up my HDTV to the component jacks, it worked great. I figured the component jacks must be only for use with HD. I moved the SDTV to the bedroom and hooked it up to the component jacks in the SD receiver there. Same problem as before. I ran the S-video output to a DVR recorder and ran from the recorder to the TV input using component and everything worked fine. Will component outputs not work with 480P TV's, or am I missing something?
