Hi all,

I've been using the PowerDVD codec for some time and it worked well up to now, but meanwhile I experienced problems with some files (image artifacts). I made a quick test with LAV and the artifacts were gone, so I wanted to switch completely to LAV.

Unfortunately I'm not able to get it running with hardware acceleration. Playing the same file I have below 10% CPU usage with PDVD, but above 50% (up to 85%) with LAV. Setting LAV mode from native to copy-back doesn't make a difference. When I click on the LAVvideo icon in system tray it tells me that avcodec is being used, although both DXVA2 modes are available.

My system specs are as follows:
- AMD 5050e CPU
- nVidia nForce630 chipset
- ATI HD5570 graphics card
- MediaPortal 1.2.1
- Windows XP SP3
- CCC 11.9
- PowerDVD 11 / LAV 0.58.2
- Splitter and audio codec are always the LAV ones, only the video codec varies
- Renderer is always VMR9.

Does anyone have an idea what I could try to get this working?

Best regards,
myscha
