[QUOTE="CyberSimian, post: 1202814, member: 141969"] You have not said in what way they look better! :confused: A common problem with HTPCs is jerky scrolling and panning of HD content. Jerky scrolling is easily noticeable on programme credits that scroll vertically, and on tickertape newsfeeds that scroll horizontally. Jerky panning is easily noticeable when the camera pans horizontally across the scene. Is this the problem that you have? This problem was much discussed at [URL='http://www.TheGreenButton.tv']www.TheGreenButton.tv[/URL] with respect to WMC, and is usually attributed to the TV datastream switching frequently between 50i and 25p, [B]and the graphics adapter not being able to switch rapidly enough to remain synchronised[/B]. I have noticed this with some HD TV in the UK when using MP (but not with SD TV). The info display on my Sony TV displays the datastream type (576i, 1080i, 1080p), and it can be quite instructive to watch a series of advertisements on ITV using the TV directly (not via MP). Some of the adverts switch rapidly between 1080i and 1080p, often many times within a single advert (usually at the points where the scene transitions occur). The graphics chips in my Sony TV have no difficulty remaining synchronised, so there is no jerky scrolling or panning of HD material visible on the Sony. I have noticed this problem with some HD programmes viewed via MP (the spooky serial "Remember Me" has a particularly bad segment at one point; I have retained a clip as a test file). I tried various settings to find a cure. The ones that eventually worked for me (with the graphics adpater that I have) are: LAV Settings: "De-interlacing mode" set to: "Force" "Hardware decoder" set to: DXVA2 (native) In "MP Config", click "Codecs and Renderer", then click the tab that you want to set ("TV Codecs" presumably), and then click the spanner icon for each of the different video types. Then you can set the de-interlacing mode and hardware decoder. I have these settings for all of the other tabs too, but I am not sure that that is necessary (which tab does recorded TV use?). Actually, when I was trying different settings, it was all a bit "hit and miss", so I hope that I have remembered correctly what it was I altered in order to get an acceptable result. -- from CyberSimian in the UK [/QUOTE]
