[QUOTE="Scythe42, post: 753280, member: 95833"] This sounds like a very old bug is returning. But I might be wrong here. Haven't followed this thread for a long time The solution back then I introduced to MP for this and similar issues was: [LIST] [*]drop a frame when it's presentation time delta to current time is > 0 (frame is late) [*]don't drop frames during DVD menus [*]don't drop fames during ff or rew [/LIST] Was any of this logic changed since the dshelper from MP 1.1.0?
