[QUOTE="serak, post: 749712, member: 69983"] Hello, when i try to play any video outside of MediaPortal (in Media Player HC), everything works fine. The same video played in MediaPortal is jerky. (Used codec is the same.) I thing, problem is with calculation of Time Rate / Refresh Rate. Best simulated is it on this video: Here is picture of video played in Media Player HC: [url=http://picasaweb.google.com/lh/photo/v09mZnqdLlLAsvH3YZWfjQ?feat=directlink]Picasa Web Albums - Serak[/url] Used filters: [url=http://picasaweb.google.com/lh/photo/2wzpkCx_WaRLEiyv40ljhw?feat=directlink]Picasa Web Albums - Serak[/url] As you can see, graph is perfect and Frame Rate = Refresh Rate. And the same video played in MediaPortal. [url=http://picasaweb.google.com/lh/photo/jsEFYuKfsx4W1KoK97a-ow?feat=directlink]Picasa Web Albums - Serak[/url] Used filters: [url=http://picasaweb.google.com/lh/photo/5teCh-AcbPzSC22nc2k2xw?feat=directlink]Picasa Web Albums - Serak[/url] Graph looks terrible. Picture is jerky. "Refresh Rate" = 50Hz and "Frame Rate"fluctuate 35-43fps (Video is originaly 25fps.) Here is my refresh rate settings: [url=http://picasaweb.google.com/lh/photo/iu5B6Q2OzCZ8EcBKqb7bFg?feat=directlink]Picasa Web Albums - Serak[/url] [url=http://picasaweb.google.com/lh/photo/00p7v6IXFpkBMIyjBCeBSw?feat=directlink]Picasa Web Albums - Serak[/url] I tried to change codec ffdshow to PowerDVD or another, but with the same result. I'm really desperate. Any help will be more than welcome. Thank you. [SIZE="1"][b]MediaPortal Version[/b]: 1.1.3.
