so, I have a problem: some movie I have dwl from ftrck can not play only the first some-10 seconds. The file is - let's say - 200mb and when I try to play in MPClassic or WMP it shows only the first 50sec. Already when I start it starts projecting only that length. And here is the real surprise: when I move the position tracker by hand and jump some in the movie, new never seen pieces appear. what is that?
