More digital cable advisor woes

[gleep52]

I posted this on another site, but was hoping to find more feedback here...

The problem: When I run the digital cable advisor, it tells me my graphics card fails stating it doesn't support content protection. <sarcasm> YAY! </sarcasm>

My setup: I have a 64bit system with 18GB of memory, ATI HD6870 card with 12.10 drivers (latest), and two monitors - a Dell 2407WFP-HC (Digital connection (DVI)) and a Dell 2408WFP in analog mode (VGA).

What I've done: First thing I tried was unplugging the VGA monitor. I left it unplugged for the remainder of these tests. Rebooted. Reinstalled 12.10 drivers. Upgraded to 12.11beta8 drivers. Uninstalled all ATI drivers, started with clean install of 12.10 (not beta). Switched monitors (moved the DVID connection from the 2407 to the 2408), still fails tests.

Everything hardware wise looks like it should be working but it's not. I can playback clearqam at 1080 without any problems... but I just picked up a HDHomerun Prime and wanted to get the MCard from my local cable company. Will I not be able to watch encrypted channels in HD (or at all) if media center doesn't figure out that I am in fact, compliant? Am I understanding it correctly that ClearQAM will still work in HD playback even if my graphics card fails this test - it's only encryptedQAM chans that will be blocked? How to remedy this?

I also tried changing my resolution to 720p output and that did not work either.

Any help or pointers is highly appreciated!

Does your motherboard have HDMI? If so you could temporarily disable the ati card until you run the digital cable advisor.

Nope - no onboard video. Just the ATI card.

It has did it to me to run fine under 7 I think it the test that Broke

This used to work in Win 7. Not sure about Win 8

Thanks for the link - I found that site last night. I plan on trying it when I get home from work today. I also bought a few new cables and even a new monitor for testing. My old Dell ones are getting pretty old. *fingers crossed*

I posted this in the other forum, so I'll cross post it here. The 2470WFP-HC is not HDCP compliant at 1080p. It is only HDCP compliant at 720p. Therefore, you need to feed a 720p signal to the monitor in order to pass the DCA. The resolution should be adjusted in Windows in order to pass the DCA. I'm not sure if the resolution in WMC needs to be set to 720p as well (in order to pass the DCA), but I know it will need to be if you intend to watch any protected content in WMC. So try it both ways...set only Windows to 720p and see if that helps. If not, set both Windows and WMC to 720p.

Additionally, the DVI input only accepts progressive scan signals because it lacks a deinterlacer. The component input has a deinterlacer, but of course component is not HDCP compliant.

Hi Richard,

Thanks for the post - but I found the problem! It was with hyper-v. I am running windows 8 with hyper-v. WAS I should say. Uninstalling hyper-v now allows the HDCP verification to pass! So both of my monitors are HDCP compliant... (Both DVI right now).

So it looks like there might be a hardware sharing/video driver SNAFU that needs some work. I'm guessing that means it falls in MS's court.

Hopefully this info will prove useful to others with the same problem.

Well that directly contradicts the information that I found (which states you need to push 720p, not 1080p). That's a bit weird. But hey, as long as it works that's all that matters.

[gleep52]

I think it might be that I can push 1080P, just not display the WMC version of 1080i... I can get my display to do 1080i through the catalyst control center. My system can playback ClearQAM data just fine (which is 1080i)... so maybe resolution doesn't matter for source vs playback (it gets upscaled?) Who knows - I'm happy as it is
