HDCP Compliance with WinDVD High-Definition Advisor

01-13-2008, 07:45 AM
So I've rigged together the following configuration:

* Hitachi 42HDS69 42" Plasma HDTV (supports HDMI, HDCP)

.. and a computer having ..

* Quad core Intel CPU
* 4 GB RAM
* Blu-Ray reader / DVD burner
* evga nVidia GeForce 8800 GT
* Windows Vista Ultimate
* Two LCD monitors (19" widescreen, 20" standard)

The Blu-ray reader came with WinDVD LE for Blu-ray. I haven't tried playing Blu-ray discs yet, but I came across a WinDVD High-Definition Advisor software download that inspects your current hardware configuration and lets you know whether or not your system is cable of showing hi-def content from Blu-ray or HD-DVD source.

I connected the computer to the plasma HDTV using a DVI-to-HDMI cable. nVidia's software allowed me to select 1080i refresh rate and resolution, and it looked fine on the plasma screen. Then I ran the Advisor.

The Advisor told me everything checks out, except for only one thing, and that is an HDCP comlpiant monitor. First it told me this before I connected the HDTV, then to prove to myself that switching from the 2nd monitor to the plasma screen would fix the job. It didn't.

What have I done wrong? Any ideas?

The Advisor could be making an error. At least test with a BD disc first before worrying about what's wrong.

K tried a BD disc. It says, "Your VGA device does not support high resolution playback. Please lower your screen resolution and try again."

Please help?

Weird. I tried it again in a window and moved WinDVD to the TV (2nd monitor) before it had a chance to fire up (whereas before I had moved at afterwards), and it ran, and I double-clicked the window to go full-screen and it still ran. I guess it's working, although it's hard to tell if it's at max resolution; looks nice but almost looks more like like DVD resolution.

Now my problem is I can't get it to go 5.1 channel surround with my optical. Windows Vista tests the optical audio fine, but WinDVD does stereo-only. What's going on? I know that this version of WinDVD is the "LE" (Limited Edition) version, but shouldn't 5.1 channel surround to optical be a pass-through method? Isn't that, likely, really simple for a BD player to do?

Alright I dropped another $99 on PowerDVD Ultra. Works, although I still have audio trouble. Using an E-mu 0404 USB external audio device which has an optical SPDIF output but PowerDVD isn't letting me select it. I choose SPDIF and it seems to be binding to my motherboard's SPDIF output which I'm not using.

I never dreamed I'd be spending more on a hodge-podge of hardware, software, and DVI/HDMI/optical cables to get Blu-ray support than if I just bought a darned standalone BD player, and even still I'm having trouble. *sigh*

Have you tried the motherboard's SPDIF?

No, perhaps that would work.

Incidentally, I've since bought a full-blown Blu-ray player and still had no digital audio while trying the same disc. I had HDMI to the TV, then Optical Out to the receiver. Nothing. But I tried adding optical out from the Blu-ray player directly to the reciever--so HDMI to the TV is only used for video--and that worked.

I don't get this. I can live with this, but I don't like it, and I don't get it. It's surely either some weird HDCP thing, or else it's an audio signal incompatibility. (My reciever only supports plain Dolby Digital and DTS 24/96.) But has anyone ever heard of this? Like, does the HDCP spec somehow establish some kind of odd rule that there can only be one physical hop? The answer might explain the PC issue with motherboard S/PDIF vs external audio unit optical S/PDIF as well.
