I've been getting two identical copies of a 'real' new show (Shining Vale) on Starz C 354 every week.
There is only one timer. I just looked, it shows scheduled to record on this Friday 10pm and again on Saturday morning at 1:30 am. Both shows are on STZC 354. Both are identical including the Season, Episode, date, description.
Never happened before H316.
I've even tried deleting the timer, finding the show in the guide and setting a new timer. Nope, still schedules two recordings of the same show.
I imagine it could be with the Guide supplier marking both shows as new.
