What steps will reproduce the problem? sample -> http://www.mediafire.com/?vsqh444wjb1j8by script
LoadPlugin("..\ffms2.dll")
video=FFVideoSource("..\video.mkv",threads=1)
video=Trim(video,1216,1400) What is the expected output? What do you see instead? at the begining there are atleast two repeated frames. (1216 is a location of keyframe according to ffindex) What version of the product are you using? On what operating system? r700

My current workaround is again

video=Trim(video,1216-1,1400) #Detected Key Frame - 1

Still broken... again

FFMS_VideoSource::HasPendingDelayedFrames() doesn't guess the right number

Adding +2 to the guessed delay fixes everything. But how to know that?

And it's probably kinda fixed.
