DirectShow

Hello people
I am running movies avi,and mpegs with DirectShow
i am loading many movies with RenderFile
but show just first with IMediaControl ::Run();
and something strange is happing
the movie is running but on him i see the first frame of last movie that had been loaded
for example
i am loading movie1,movie2,movie3,movie4
and then run movie1 but on it there is first frame of movie4
i am shure than no simple bugs in my program i mean i dont explicity run this movie
if somebody can explain it would be nice
thanks Oleg
