I have just hooked up a Explorer 3200 digital box, and ordered the NHL Centre Ice package i have a few channels available but the other ones are "currently not available" according to the message im getting...is this an existing problem or is there anything i can do to get them to come in

Moogle its a signal issue.. or your STB is in Broadcast mode. Call Rogers.

Sounds like SDV again.
Do a search on SDV
