-af volume doesn't work with copy because it's a copy !!
In fact I don't have home cinema, then I will enconde in 2 channel 
stereo PCM. Like it isn't a copy -af volume should work.

I just begin with mplayer, it's a little complex now.
I will have soon a Tv satellite card and I will dedicate myself to make 
it work, and I presume that it will be a full time job ;-)

Thanks for your help.
