Looks like I might have to subscribe to HBO for a month

HBO Checks in With Hockey Series.

From the linked article:

HBO is lacing up its skates and joining the NHL in drumming up interest in the league's midseason marquee event, the Winter Classic.
HBO sports is producing a four-episode series, 24/7 Penguins/Capitals: Road to the NHL Winter Classic," which will debut Dec. 15.

This might be my Christmas present to myself.  Plus, in addition to the behind the scenes stuff, this should be one hell of a game.
