I added Premier Sports last week, but it has only added to my main box, not my second box. the second box shows all of the other sports channels I pay for. can't get through to anyone to discuss.
You don't say which type of boxes you have , however with the V6 you can try the following
Using your remote control
Help & Settings > Help > Virgin TV > go up to the top of the screen then TV Care and press OK > Missing Channels.? > Refresh my channels list
