[QUOTE="tourettes, post: 490566, member: 10858"] Odd result as it should be exactly the same when application specifies the v-sync enabled (as MP does always). - Was the clip real 24hz video file (or actually non-24hz clip, like 23.9xxx)? - Were you using SPDIF / HDMI ( audio also )? - Does the bug go a way (when v-snc is forced) and you use analog audio or decode the audio to stereo mode with some audio codec? Is this a driver issue on ATI side? At least Arcsoft player has had similar effects with ATI and 24Hz + Blu-ray (just search AVS forums). This issue is caused by multiple different issues (like the users have already reported). [list] [*] Audio codec issue [*] Driver issue (with forcing v-sync on), maybe HDMI audio & video gets out of sync? [*] Bug in drivers (as 24 vs 23.9xxx setting as display frequency solves the issue) [*] Bug in MP [/list] ps. now as we have one developer (gibman) who is able to reporduce the issue we might be closer to the solution :P (in case it is a MP bug) [/QUOTE]
