serial sports team recording misses some games

I set my DVR to record all of my local NHL hockey team's games. This works for all games broadcast on my local sports channel. However, occasionally, the game is broadcast nationally, and though the game is listed in the Xfinity Guide, a different program is substituted, as if the game is blacked out. The game is still broadcast on the local channel, but the DVR chooses to record the empty national broadcast.

Is there a way to force the DVR to record on the local channel?
