[QUOTE="Owlsroost, post: 841478, member: 83973"] What's happening when the video 'stops' (from the logs) is that the supply of video samples (decoded/deinterlaced frames) to dshowhelper isn't fast enough. They are arriving too late to be used, so dshowhelper has to drop them - this is what the "Dropping sample from the past" messages in evr.log mean. These messages are happening about every 40ms - it looks like something is throttling the sample delivery rate at (or just below) the video frame rate (for some reason), so it can never 'catch up' and the video freezes. I have a few thoughts about what might be happening, but I suspect the Windows DWM (Aero) is involved in this, because odd things like this mostly seem to happen with dual-screen systems (from what I've seen in logs from users) - especially when the screens are at different refresh rates.
