1) Try playing a bit with -d switch (actually not sure FB "gui"
  really makes use of that)

 

I did try -d (FB gui uses it) but it did not improved the movie speed, it did improved the input events handling a bit. 

2) Force quality to "low" (see gnashrc)

 

Did not help.

3) Implement XV hooks in FB ? (ie: hw scale up, rather than letting
  the renderer work on whole surface)

 

Can you  point me to some ware with more information about XV?

0) profile :)

Here is the profile information:

~ # opcontrol --vmlinux=/vmlinux
