It's wonky, I guess.
I have Timer Recordings for Series set up, and they seem to be skipped at times. I notice the show's icon might change, or a generic icon for that channel may be shown instead of the show's normal icon. Maybe the system thinks this is a different series or something and therefore does not record it?
The Search function, also, seems to see some shows listed under a given title, but NOT all that the guide shows.
Anyway, I'm missing more and more episodes. Unless I carefully walk through the night's line up everyday on the guide and confirm everything I told it to record is in fact scheduled to be recorded, I might miss some episodes. That's wonky.
