[QUOTE="madshi, post: 778382, member: 114920"] The 50i movies I'm watching are all h264 European broadcasts, which are all perfectly flagged, so a simple "weave" does the trick to get perfect 25p playback. This is all done via software, the GPU only has to render 25p frames. I've setup CoreAVC to output 25p via weave. That applies to all renderers I've tested. I think a lot depends on which GPU you're using. Are you using ATI or NVidia? Based on feedback from madVR users it seems that ATI has less problems in this area. Personally, the only way to get 25p playback to be perfectly smooth with my HTPC is to use fullscreen exclusive mode and presenting multiple frames in advance (in exclusive mode "ID3D.Present()" does not block, so you can present multiple frames in advance). In every other mode playing back 25p movies with 50Hz is not perfectly smooth on my HTPC. It's "ok", but not perfect. When presenting multiple frames in advance in exclusive mode, I'm getting pretty much perfectly smooth results. [/QUOTE]
