Hi Grozdan,
I'm not sure, if I understand your hint in the right way.
I tried "my" mencoder script with
frameref = 1 / ...=3 / ...=5
None of the resulting files can be played by my stand alone player
frameref=1 and 3 leads to reframes 4
frameref=5 leads to reframes 5 (in the MediaCoder video output)
The ref parameter in encoding optins decreases:  (for the frameref=1 try)

I do not know where I find the information about the frames from MediaCoder.
Any other suggestion or hint where I could look ?
Thanks
