The 819 is connected to Samsung LCD thru HDMI
I have my dish network receiver hooked to the 819 thru HDMI.
DVD player connected to 819 thru HDMI.
5 speakers (its a old 5.1 system without woofer)
DVD plays great - awesome AQ and PQ
SD channels are good too
Its the HD channels that are the problem. The audio goes really low. I dont remember if all 5 speakers had audio. Switching to SD channel works great again. One difference I noticed is that on switching to a HD channel, the front panel displays DD.
