mitsu Posted November 13, 2006 Share Posted November 13, 2006 (edited) Geforce 7600GS with latest drivers. If I select HW acceleration with any MPEG2 HD channel only black screen is shown. Audio is OK. Same thing with Sonic Cinemaster and Cyberlink DTV decoders. This problem only with live broadcast. Recordings work also with HW acceleration activated. This might be Nvidia problem but I don't know what to report. Something between DVBSource, decoder and Nvidia drivers. HW acceleration causes occasional chashes obviously caused by the Geforce card. Edit: Support.zip could not be attached because of file space limit. I can attach it later if needed. Edited November 13, 2006 by mitsu Quote Link to comment
Engelbert Posted November 13, 2006 Share Posted November 13, 2006 http://www.cyberlink.com/english/support/b....jsp?Source=DEU At Cyberlink there is a pretty little tool (free of charge), this explains whether a PC high-density-TV can or why not. Quote Link to comment

That was interesting bu did not help with the problems. Quote Link to comment
Klaus_1250 Posted November 13, 2006 Share Posted November 13, 2006 I had the same issue with the original TwinhanDTV software. Hardware acceleration + HD channel gave a black screen. You might want to try choosing Overlay instead of VMR7/VMR9 to see if it makes a difference. I also read somewhere that hardware deinterlacing + hardware acceleration could give some problems, as well as running ffdshow raw video filter + hardware acceleration. Quote Link to comment

Same thing with all overlay and VMR7/9. There must be something really wrong with HW acceleration of the Nvidia card. I get BSOD after one minute of HW accelerated watching of any SD channel.

Klaus_1250 Posted November 13, 2006 Share Posted November 13, 2006 (edited) Out of curiosity, are you using the PCI-E or AGP version? As for the NVidia drivers, I never found them to be really stable :-( Edited November 13, 2006 by Klaus_1250 Quote Link to comment

Klaus_1250 Posted November 14, 2006 Share Posted November 14, 2006 AGP-versions seem to have issues with hardware acceleration, which aren't resolved AFAIK. Lost the link, but one webstore even had a footnote on its website saying not all hardware acceleration features worked on AGP-version of the 6xxx and 7xxx series. Acoording to the Nvidia website, there should be no problem though. Quote Link to comment
