[QUOTE="myscha, post: 1022258, member: 74181"] 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 [/QUOTE]
