[QUOTE="DragonQ, post: 982290, member: 115209"] Well the default upscaling is poor. Since MediaPortal can't dynamically change the screen resolution to let your TV to the upscaling, SD will always kinda crappy unless you're sitting far enough away. I've attached screenshots showing the improvement when going from using MediaPortal as-is to adding ffdshow post-processing (Lanczos3 for luma, Bicubic default for chroma). It might be possible but I can't figure out how to do it. It looks as though ffdshow treats everything as progressive, so when it sends the final post-processed video to EVR it doesn't send the correct interlaced flags. Thus, EVR just assumes the video is progressive and you get combing artefacts due to weaving. The only way I know of to avoid this is to use CUVID, since the deinterlacing can be done [I]before[/I] ffdshow gets a hold of the video. Maybe there's another way. [/QUOTE]
