The use case is sports programming. A recent example was this past Saturday, the Ravens v. Washington football game was being broadcast on Fox, CBS, and MASN. In my case, the channel numbers are 510, 511, 576, respectively, so it only recorded the MASN broadcast on 576. My preference would have been for it to record the Fox or CBS broadcasts because they were "my" local broadcasts, from a Ravens perspective, whereas the MASN broadcast was from the Washington perspective. However, since I wouldn't really know which broadcast would be "my" local one (without actually putting eyeballs on each broadcast), it would just be easier to have them all recorded. Then when I go to watch, I can pick which broadcast I want to watch and delete the others.
Now, where it gets worse is for those times where the guide data shows a game being broadcast on multiple channels, but one of the channels will actually be showing something else at that time due to, I assume, various blackout restrictions. I see this more often with Orioles or Capitals games. For example, Orioles vs. Yankees, and it will show the game as being broadcast on MASN and YES networks, where YES is the higher channel number. But because the O's are being broadcast on MASN, my YES broadcast will end up broadcasting something completely different and therefore I end up not getting the game at all. This same scenario happens most frequently with Capitals games. It'll show as being broadcast on MASN and ESPN and/or NHL network, but again, since it's actually being broadcast on MASN, then ESPN/NHL network will broadcast a wholly different show.
So, yes, to work around all the stupid sports broadcasting shenanigans, I setup manual recordings, when I remember. I was just hoping there was a way in the series pass to say 'Hey, I don't care how many different channels it's broadcasting on at the same time, just record them all and I'll deal with them after the fact'
Thanks!
