Are you doing any switching for video in your receiver? 103D processing does a better job then the upconverting-processing of the AVR. I use my AVR for switching, then take the HDMI out from AVR to HDMI in on 103D. It cleans up the signal great on my Direct TV and my old Sony777 DVD Changer. You can feed all your video signals through the 103D and clean them up. Even my Sony777 changer goes Component into AVR, upconverted to HDMI, then fed into 103D with Darbee and out to TV. It works.
Using the connection method you describe can you still get your AVR OSD menu to appear on the TV? I want to be able to use my AVR menu to make adjustments when I want to. Do you have any input lag when you switch sources or channel surfing?
THX in advance.
