video out in xp guest

[orengolan]

I try to watch videos on a TV with my viao.

I want to do it from XP under vbox since my Fn+F7 key does not work.
in my XP, when I do right click -> properties i see only 1 monitor icon.

any ideas what is the problem?
Is it something I need to enable in vbox?

Thanks,
Oren
