[MEncoder-users] Mplayer output on main display with SSH ?

[Thijs Vermeir]

Hello,

Situation:
PC1 -> mplayer ( works OK )
PC2 -> connected to PC1 via SSH

I want to start mplayer on PC1 with the ssh connection.
When I'm start a movie over SSH there is no video on PC1, sound is ok  
on PC1.
I get this error:
vo: couldn't open the X11 display ()!

So my question is : How can I start mplayer via ssh on PC2 to have  
all output on PC1?

Thanks,
Thijs
