A followup on this following more testing. PDVD15 seems to be getting very close to using all the GPU memory. For example, one of my test MKV files with H.264 720P@24FPS the telemetry is showing 98% GPU memory utilisation under PDVD15. It crashes and spawns the cyberlink issue reporter (you must have gotten a whole bunch of them from me by now) or it will freeze and windows kernel will take control and terminate PDVD15.

When I play the same test file in say MPC-HC ffmpeg LAV filters under DXVA2 native mode, I see a peak of only 68% gpu memory utilisation. The test file plays fine with the open source software.

Hi Nullack,


I couldn't reproduce this issue. I tested with the same build as yours.
The CPU performance is normal on my side, so I don't know, is it a Software or a HW issue.
Can you please provide me a video sample, or your test mkv files?
Thank you

Kind regards
Hicham

Hi Hicham I've been doing more testing. I can confirm that PDVD15 is seriously broken and I have info on the way to replicate it. I simply want PDVD15 to do what it is advertised to do and I'm going to keep at this until I've got working software. I'm going to do a support ticket on this problem because it makes PDVD15 effectively broken for any video playback.

What I have discovered is this. After I totally uninstalled PDVD15, I was super careful to delete everything, including my old user preferences. Then I installed the original PDVD15 version, rebooted, applied the latest patch that you released to prod and rebooted again. I then checked windows update and did the cumulative windows 10 update to bring my OS to the latest which is 10586.11 and this again is a prod build from Microsoft. I then also did a complete uninstall of my Geforce GTX 960 drivers, rebooted and did a new clean install with default nvidia settings of their latest drivers.

Everything was fine on reboot. In PDVD 15 I can playback all my video 100% fine. True theatre, the UI, everything was OK in my testing.

The problem with the default settings is that the NVIDIA 3D stereoscopic mode is not enabled, and there is no 3D resolution configured My 2D desktop is 4k UHD @ 60 Hz via HDMI 2.0. If I try to playback 3D blurays in this mode, I will get nothing but 2D playback. I am *forced* to enabe the 3d mode and configure a 3D resolution to see 3D. Noting that my 4K UHD does 3D in HD being 1920x1080@24fps.

So I did that setting to enable 3D to see 3D. This is the key to replicating the problem. When its enabled, Cyberlink PDVD15 breaks. What specifically I mean is this. I have 3d enabled in the nvidia control panel, with a valid 3d resolution. However Im in my normal 2D 4H UHD @ 60 hz desktop. I only ever run a 3d desktop while full screen in pdvd 15 with a 3d bluray being played. All other video playback is in 2D UHD. So Im in 4K 2D UHD @ 60 hz, with the 3D stereoscopic setting enabled. Try to watch any orindary 2D video, often it will crash right away with the cyberlink issue reporter being spawned. Or PDVD 15 will try to playback the video, and it will be a stuttering mess, sometimes taking out the GPU all together with OS saying stuff like the following about both my intel embedded GPU and my discrete geforce GTX 960 GPU being flagged as:

Windows has stopped this device because it has reported problems. (Code 43)

My point is that you advertise you support windows 10 and you support 3D bluray disc playback. In good faith, and in trade practices law I reasonably expect that to be true. Previously Cyberlink support have tried to cop out of this situation with saying that its all Nvidias or Microsofts problem. Im going to keep at this until its fixed. Some questions please:

1. If Cyberlink powerdvd 15 is OK to use on Windows 10, why do Microsofts own tests fail on your software for device driver verifier from Microsoft which as I understand it, it required to be passed in order to be Windows 10 platform ready? How can you claim you support Windows 10 when you fail Microsofts tests to determine platform readiness because of coding errors in your kernel mode processes bundled with PDVD 15?


2. Why cant your support actually help me, and work with me, on fixing this?


3. If the root cause is indeed some sort of OS or middleware dependency, how exactly can you be sure of that? And where precisely is the error? If for example it is a problem with Nvidia drivers, why arent you firstly identifying this in your development and testing phases and why is it occuring in production releases with end user customers beating their heads against a wall for hours on hours trying to get a grasp on the problem? Why arent you working with NVIDIA?


4. Since Im never going to give up on this, if you want me to campaign to Nvidia on it, I will. I have in the past done this when Nvidia drivers were bluescreening in prior builds of their drivers when I was previously trying to get 3D bluray disc playback using PDVD15 to work. I have email address contacts with Nvidia staff. I sent them memory dumps of the kernel memory and my displays EDID dump. They fixed the blue screen stop errors in later builds. There is no longer any stop errors coming from Nvidia drivers.

Im trying to provide Cyberlink an opportunity to show why you actually are providing the worlds best media player as you claim.
