In general this is a no no as most video apps usually need direct access to the hardware which the Virtual Bios doesn't see.
I was wondering however has anyone managed to get o USB TV stick working on a Virtual Machine yet whther using VBOX or VMWARE.
If you did what is the TV stick you are using and what software did you run for the TV application.
Would the TV function in Windows XP Media Center edition work in a VM.
Note that the BBC Iplayer works in a VM (Vmware) so SOME video will of course work in a VM.
