seen where depending on where the show is in the priority listing effects whether it has upcoming shows or not as well? had instance of show with 18 recordings pending when moved to the bottom all sudden had no recordings. when moved back the recordings came back. Also has effects if to many shows are listed to record at the same time.
Would need more information, perhaps screenshots. If you have too many recordings scheduled at the same time then recordings at the bottom of the Recording Priority will not be recorded if there are conflicts with other recordings that are higher in the Recording Priority list.
if a recording is set at the top of the list for priorities it will record shows for today. if set at the bottom it selects other days to record.
