Hi all,


I've recently installed Windows 7 and GBPVR on my HTPC (previously WinXP + GBPVR) and was looking at the codec options.


I was hoping to use the built-in MS DTV-DVD codec as I believe it uses hardware acceleration when used with the EVR renderer. When I tried the MS codec and GBPVR's EVR renderer, I got no picture or sound. Using the VMR9 Fullscreen-Exclusive renderer and MS codec works but the CPU utilisation is around 60% - i.e. there's no hardware acceleration going on.


I tried installing PowerDVD 9 Ultra, but after install it's H.264 codec wasn't listed as an option for GBPVR to use. In the end, I went back to the codec from PowerDVD 8 with the EVR renderer, and everything seems to be fine - 10% CPU usage and good quality playback.


Should I be able to use the MS DTV-DVD codec with GBPVR's EVR renderer to get hardware-accelerated H.264 decoding, or does the codec only provide hardware acceleration when using Media Foundation (or whatever it's called) with MCE?


Confused!

Just a comment on PowerDVD - from version 8 (there is an update, don't install it!) the software blocks its decoder from being used by other applications.

The codec is supported by GB-PVR under Windows7. I'm not running Windows7 at present on my PVR but have used the RC in the past and had no issues.

I know sub does post on here so he may have some comments but your best bet might be to post on the GB-PVR forums.

Mauricio - That'd explain why the Cyberlink codec wasn't listed in GBPVR when I installed version 9! Did your efforts to get a codec-only license (and discount) from Cyberlink come to fruition?

Steve - yep, I'll post something on the GBPVR forums too. It sounds like EVR + MS codec should work.

No, nothing came out of that. They offered me a "discounted" PowerDVD 7 that was more expensive than the latest version.
