DSTV CUTS OFF PRE-RECORDED SHOWS ON PVR

I set my PVR to record entire seasons. On more than one occasion (most recently on 11:22:63 and Vinyl) the recording stops with over 12 minutes of the show remaining. For the amount we're forced to pay for a bouquet of mostly unwatchable ****, the least they can do is ensure that a tv show can be recorded from start to finish. Unbelievable. If it wasn't for the sport channels they'd rightfully be out of business.
