Do I need to buy another set top box to be able to watch Virgin Media channels in another room?

Question

I want to be able to watch different channels in my bedroom.

Answer 1

Yes.

Answer 2

If you want to choose your channel independent from the main room then yes, you need a 2nd box.  If you want to watch cable channels in another room you can get a video sender and use that, including changing channels, but you'll have the same channel on as in the main room.
