[maxmsp] [jitter] Framesync issue ( frame vs. frame_true)

Hi list,

I encountered a very weird problem with the jit.qt.movie object. I'm  
trying to build a framesync video player over net.maxhole. Everything  
just worked great but now I have this problem :

- Loading in a H.264 movie (in my case a movie trailer I found, but  
problem occurs with all files I tried)

- Both [frame 250] and [frame_true 250] take me to the same frame, so  
far so good

- Loading in a movie with another format/codec (in my case I tried  
with the crashtest movie from patches/media)

- [frame 250] and [frame_true 250] refer to different frames.

- Loading back the original/initial movie also refers to different  
frames

I tried to load in movies via [dispose,clear,read] command to be sure  
no settings have been left by the previous movie, still nothing will  
work but to delete the qt.movie object and put it back on stage. So,  
is there any command to totally reset the qt.movie object. Or is  
there a way to work around the frame vs frame_true issue (the  
difference is not just a few frames but might be over 500 in some  
cases !).

The software I'm building should be able to cope with flexible file  
formats so it should be great to solve this issue

Here's a patch to reproduce this issue :
