Virtualbox video capturing

[Reza Roboubi]

Is it possible to capture a video that plays in XP under Virtualbox, 
together with audio?  How about dumping a video presentation of the 
complete screen of the virtual machine (again, while recording audio out 
of the virtual audio device?)

Also, can either Virtualbox or KVM/qemu fork input/devices into guest 
and host simultaneously (so that mplayer captures audio under both guest 
and host?)

Thanks a lot.

Reza.
