I've just cut over to SAF5 (101201) from Shark007 and am having some trouble getting some of my 1080p .mp4's to work properly under DXVA.&nbsp; First, I am getting extreme stuttering in all my 1080p .mp4 content under ffdshow DXVA. A MediaInfo dump for a representative file is attached. I get extreme frame-drop/stuttering with cpu utilisation hovering around 50-65% (indicating poor DXVA speedup). By contrast, using Win 7's built-in MS DTV-DVD Video decoder in MePo config results in silky smooth playback with &lt;10% cpu utilisation. I would be content to just use the MS decoder; unfortunately however, using it alongside ffdshow for audio results in audio sync issues. I get into an out-of-sync condition any time I skip fwd or backward in the video stream. The MediaInfo dump for a 720p .mp4 file alongwith the filtergraph used by MePo while exhibiting this behaviour is attached. Its worth mentioning that there are no audio sync issues if ffdshow video and audio are both used together. So, I'm in a bit of bind here. I need/prefer the MS decoder given its superb IQ and the difficulty ffdshow DXVA is having with my 1080p content, but using the MS decoder results in unacceptable audio-sync problems. Any help and/or guidance here is much appreciated. Thanks in advance, and do keep up the great work!</blockquote>
