Hi from Germany

This question seems to be a cheap one at first, but I'm actually having a lot of problems here.

I bought PowerDVD 10 Ultra Mark II a few weeks ago.
My video card is an "old" PowerColor ATI HD4870, latest Catalyst drivers (10.12).

I can't use the hardware acceleration found under video options in PowerDVD or else Win7 (x64) gives me an instant BSOD (STOP: 0x116 - atikmpag.sys). As I can't figure out why this is happening (only PowerDVD seems to be affected) I chose to simply disable HW acceleration.

The problem here is, PowerDVD doesn't remember this option correctly. So I play some BluRays and after a while I get back to my BSOD. When I recheck options in PowerDVD, HW acceleration is back on.

The only way I could work around this problem was to disable write access to HKEY_CURRENT_USER\Software\CyberLink\PowerDVD10 in registry. This way no settings can be changed by itself and HW acceleration keeps disabled.

Could you please try to figure out what's causing this bug?

Or could someone tell me why I'm getting these BSODs in the first place?

Thanks a lot!

Regards,
Alex

Hi,

well, it can't be an HW issue, I don't have any problems with other players using ATI Avivo.

I tried with different Catalyst drivers but it's always the same, so I think it's more like a problem with PowerDVD's codecs in conjunction with my video card.

I can live without HW acceleration, the only problem is this bug which reactivates HW acceleration by itself.
Could you please look into that reactivating issue?

Thanks,
Alex

P.S.: Maybe I'm gonna contact customer support, but I doubt this is a problem with my PC

Hi,
in PowerDVD the use of DXVA is mandatory on supported VGA (like yours).
There is no way to disable it (DXVA). Any setting in the Registry manipulated manually may cause unwanted side-effects.

BTW - there i a German speaking Forum as well - just need to switch the language of the forum in the top right

please also check this thread and provide more information:

A BSOD is very liikely a sign that some HW/Driver isssue happens in your system.

Well,

forcing "UIUseHVA" to be 0 in registry at least keeps the checkbox unchecked and PowerDVD running - I take my chances

Hi,
sorry but we do not support "simulated" BD Drives.

for the BSOD issue you may use Google:

I tried a DTS test BD on my HTPC (which has an ATI HD5400 series video card) and I had no problems with that.
But this PC here (ATI HD4870) I'm talking about doesn't have a BD drive so I had to convert the test BD to an ISO for this to work.

Well, anyway. The ODD drive is not important with this problem.
This also happens when I try to play a DVD in one of the regular drives...

Hmm.. those links aren't of any help, sorry...
I don't have any problems with my hardware, games play just fine, no overheating or overclocking issues.
I still think this is related to PowerDVD in combination with my video card

Well, my registry tweak is working, CPU has to do more now, but at least I can watch DVDs here.

Greets,
Alex

I have problems with HW accleration on my laptop with Geforce 8600M GT in it. Blu ray playback is just jerky with HWA on... And I use the newest drivers, a real Blu ray driver with real, original Blu ray Discs...
