dvr not recording series - DirecTV

I set the DVR to record a new series in Ovation two weeks prioir to the premiere. I set it to record first run episodes and keep 5. It never recorded the premiere, the next two new ones and told me that there were no future showings of any epsiodes. I had to go in and manually find the ones I missed as wel as the newest ones and set tthem to record. After I did so, the DVR still said that there weren't any episodes available to watch? What in the world is going on and why won't it record my show? There are no conflicts with anything else set to record, but even if there were our DVR model is supposed to be able to record 5 shows at once.
