You posted your thread in the "Articles" section, which is for Articles & Information, & is an area where all posts are moderated for approval.
I have approved it & moved it to "Cable TV Services".
Virgin Media STBs can only legitimately be supplied by Virgin Media, to genuine Virgin Media customers.
They remain the property of Virgin Media & should not be bought/sold.
You cannot just buy one off eBay or wherever & plug it in.
If you want to get cable TV for your son's room, I suggest you contact
Virgin Media 
To prevent this thread going into detail about discussing the use of illegitimately obtained STBs, I am going to close it.
