yes, my PCI Geforce 8400 card on GPU G98 can do 10...@50 but with the simplest bob deinterlacing only. I prefer to use more advanced deinterlacing algorithm - temporal_spatial or temporal. But with them I have jerky video > .. But you might get better results if you outputted 1:1 interlaced material > using 1080i50 mode and let the LCD tv do the deinterlacing.. Yes, exactly what I want to try, But I couldn't run properly 10...@50 - even in xorg.log I have the report about validated 10...@50 mode - my LCD TV Philips 9703PFL reported about 1080p source from hdmi > Not sure if that's possible with Nvidia hardware/drivers. http://us.download.nvidia.com/XFree86/Linux-x86/185.18.29/README/chapter-19.html yes it's possible Chapter 19. Programming Modes The NVIDIA Accelerated Linux Graphics Driver supports all standard VGA and VESA modes, as well as most user-written custom mode lines; double-scan modes are supported on all hardware. Interlaced modes are supported on all GeForce FX/Quadro FX and newer GPUs, and certain older GPUs; the X log file will contain a message "Interlaced video modes are supported on this GPU" if interlaced modes are supported. Note that when validating interlaced mode timings, VertRefresh specifies the field rate, rather than the frame rate. For example, the following modeline has a vertical refresh rate of 87 Hz: # 1024x768i @ 87Hz (industry standard) ModeLine "1024x768" 44.9 1024 1032 1208 1264 768 768 776 817 +hsync +vsync Interlace Goga Linux/VDR форум http://www.forum.free-x.de/wbb/index.php?page=Portal _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
