[QUOTE="Owlsroost, post: 609560, member: 83973"] Thanks for all the explanations :) I'm [B]not [/B]trying to fix the 'ReClock vsync correction not working' problem (I don't use ReClock vsync correction myself because I've never managed to find a vsync 'sweet spot' that works for all material and codecs - e.g. if I find a good setting for 1:2 H.264 it messes up 1:1 HD MPEG-2 - and vv). I set out to try and fix/alleviate some of the 'bursts of judder' problems I was seeing, and also make sure (as a side issue) that the code accomodated the 'render clock' changes that ReClock makes e.g. the +/-4% PAL speedup/speedown - without breaking any vsync correction the dshowhelper tries to do internally. I've worked in the video/audio hardware design field for years, so I fully appreciate that video/audio synchronisation and vsync alignment in Windows is a much bigger mess than the MP dshowhelper can hope to fix :) Tony [/QUOTE]
