(I am definitely in the "Beginners" category, so please keep it kindergarten simple!) My setup: Sony KDF-E50A10 TV (7-yrs old), DirectTV PVR HR-20-100, Sony Blu-Ray BDP-S350 (1-yr old), brand new Denon AV receiver AVR-1912 (replacing a very old Onkyo that had only optical connectors). Three new Mediabridge Ultra Series High-Speed HDMI cables. I paid for help setting up the new receiver. Nice guy, but he is stumped, too. PVR: HDMI cable to receiver (SAT/CBL), Blu-ray: HDMI cable to receiver (BD), receiver: (Monitor) HDMI cable to TV. Both the PVR and the Blu-ray are using TV's Video 6 input.
Satellite works fine. Blu-ray is dead in the water. Black screen and no audio. Any ideas anybody?
