When watching any media, be it live tv, recorded tv, or a film from HD, I have very occasional "micro-stutter" I believe is the right term; basically it looks like a frame is displayed twice. This only happens once every few seconds, and is only really noticeable on scrolling text (the bottom of BBC News, for example ) or in panning scenes. I'm convinced it's nothing to do with refresh rates; I have turned on Dynamic Refresh Rate, and the TV is at 50Hz (for TV, I'm in the UK), and 24Hz for my film in an MKV, which matches my sources. Pressing Shift-1 shows stats and the red line is completely flat. It does not move when this stutter happens, the entire scrolling graph just halts for a fraction of a second along with the rest of the image. The amount of "Drops" does not increase either. It's almost like it's happening in the TV rather than MediaPortal, but why would this be if the refresh rates are matched? Random things I've tried with no success: * Every different video codec available to me (ffdshow, ffdshow DXVA, MPC, PDVD11, Microsoft DTV-DTD) * Every different audio codec available to me (ffdshow, Microsoft DTV-DTD) * VMR9 and EVR video renderers * MP Audio Renderer * Setting MediaPortal to RealTime priority, setting affinity to 1 CPU It also happens in Debug mode, logs from which are attached. Any clues? Anything at all? Small edit: just forgot to mention that I tried recording a few seconds worth of some scrolling movie credits off live TV, and repeated replaying of it shows the stutter happening in a different place every time; so it's not the source. Thank you! :S [/QUOTE]
