In this case running the test, the component cable ran directy from the DVD to the TV bypassing the receiver, the HDMI cable was still able to carry the HD audio from the DVD to the receiver while the component cables were carrying the video from the DVD to the TV.
I may have to test running HDMI from the DVD to receiver then component from the receiver to the TV to see the results.
