Why does the Blue curve PVR record 4 different channels of the same NFL game?

I can't for the life of me understand why this hasn't been fixed. I have a series recording for NFL playoffs. When I go to the recorded programs, I see that it's recorded the same game on 4 different channels. Yes, I know there are "workarounds" for this, but it should have been fixed years ago according to what I can see on this forum. It's *shocking* that it's still an issue. It fills up the PVR and won't record other scheduled shows.

@nevinet -- as a simple work-around, check the settings for your recording, to look for the "all channels" option versus one specific channel.
