Well I've found a confusion in the lavc opts in the man documentation.

-----Copy&Paste---

aspect=<x/y>        Store movie aspect internally, just  like
                    MPEG  files.   Much  nicer  solution than
                    rescaling,  because  quality  isn't   de-
                    creased.   Only  MPlayer  will play these
                    files correctly, other players will  dis-
                    play  them with wrong aspect.  The aspect
                    parameter can be given as a  ratio  or  a
                    floating point number.  
                    Example:
                    aspect=16/9, aspect=1.78
                                        ^^^^
---------
This number is a decimal number, and its slightly different that 1,78
in mplayer command line 1,78 is not equal at 1.78 and when doing:

mencoder -v -dvd 1  -ovc lavc -lavcopts 
vcodec=mpeg4:aspect=2.35:vbitrate=1340:.....
                   ^^^^^
this command line don't works, but:

mencoder -v -dvd 1  -ovc lavc -lavcopts 
vcodec=mpeg4:aspect=2,35:vbitrate=1340:.....
                   ^^^^^
works fine. 

In the DOCS dir in encoding.html  there is a final text explaining the 
:aspect=16.0/9.0 again, and it must be :aspect=16/9 or :aspect=16,0/9,0 for 
lavc opts internals.

Perhaps is obvious for all, but for a newbie like me, confused a lot when 
trying to assimilate all contents of the mencoder theory....

Thanks very much for your attention.
