Deinterlacing at any level makes the picture unsharp and there is some really hard to notice microstuttering (CNBC stocks text that scrolls horizontaly doesn't scroll smooth like when watched over the IP-TV's service provider STB). I use the EVR display mode and through testing found out the following: 1. when disabling deinterlace under MP configuration\Television and setting "output as interlaced content" or something like that under MPV Video Decoder settings I get a sharp picture and no stuttering and therefore smooth READABLE scrolling text but also get dropped frames every 5 seconds and then the picture stutters which makes T unwatchable with these settings. content is played back at 50fps. 2. disabling "output as interlaced content" under MPV Video Decoder configuration and turning Deinterlace option to auto I get no dropped frames but the deinterlace filter makes the picture unsharp and content is played back at 25fps - no smooth scrolling and unsharp text (I currently use this setting as ever other one is worse). I found out, when I set MP to start on the PC LCD monitor (refresh rate 60Hz) and set the options like in point 1, there are no dropped frames and no stuttering and the picture is sharp @ 50fps (50Hz interlaced PAL content). Now the funny thing is, I cannot understand, why Live-TV stutters and is dropping frames when watched on the TV, where the refresh rate equals the fps and when watched on the LCD monitor@60Hz there appears no dropping of frames and its silk-smooth and sharp. Any advice, what can I try to solve this problem? TV stream 720x576@50i ---(no deinterlacing filter)----> TV 720x576@50i -> stutter, dropping frames every 5 seconds but best quality otherwise TV stream 720x576@50i ---(no deinterlacing filter)----> LCD any resolution@any refresh rate -> superb quality without stutter and dropping of frames Maybe it's the EVR, but under VMR9 I don't get any picture at all. Every other codec/configuration gives only worse results. Is this a common issue? [/QUOTE]
