Hello and thanks for your comments.........
I have been bashing my head against the wall with HDMI issues.... I know I am not alone and yes it is pretty silly that supposedly an "industry standard" connection would have such poor support among manufacturers....
However, I have had the following results....
1 - Connecting Sony CX995V (400 DVD upconverting mega changer) via HDMI I get both Video and audio..... hurrah! However, I think the video PQ is not as good as my Oppo 971.
2- Connecting HD-Tivo (HR10-250) via HDMI I get video, but NO Audio! I have had DTV send me 4 replacement Tivo's and they all do exactly the same thing!
3- Connecting Toshiba HD-DVD player via HDMI... now it really get weird.
A- With no disc in the player, the player boots and I get the NO DISC screen and can access the setup menu's IF I have selected 1080i. If I select 480p or 720p I get no video image at all. If I open the menu under 1080i and then switch resolutions the video goes away...
B-Then if I place an HD DVD in the tray and close the player loads and the front panel reads HDDV D and that is exactly where the player stays... most of the time pushing any button on the remote or the player does nothing (occasionally you can access the open/close button) and you have to hold the power button down for 10 seconds to power down the player. I have repeated this process with all 4 HDDVD's that I currently have.
C-If I boot the player (after one of the hard re-sets) with the DVD in the player and the HDMI connected directly to my projector (instead of through the Denon 2807) then I get video.
Obviously no audio as the signal is going straight to the projector.
Perhaps I should mention that via Component and Toslink or Coax audio the player is superb! (but who wants to use a less capable connection?!?)
The problem is I am not sure if the problem is Denon's fault, Tivo's fault, Toshiba's fault, or a little bit of fault spread around to all of them! The fact that at least the Sony 995 works gives me hope that it is not ALL Denon's fault........ but I am still far from a happy camper!
