I had a similar problem yesterday. Tried to add "Crusoe" via the online scheduler. I set to "Definitely Record" and when I got home it had put it at the top of my list. But all I noticed my daily recording of NBC Nightly News, (Both, keep just one,) had all but disappeared from my todo list. When I checked the prioritizer it said no upcoming episodes. After playing around deleteing the Nightly News SP and Crusoe SP, I would exit out and go back in and the SP were still there. I even tried deleting and readding them but the default recording options I had set would not stick and the old rules would be applied AND the SP would be prioitized from where I had originally had them. I then tried adding random shows and they would be prioritized halfway in my list. I RBR'd and had no luck. On a whim, I tried reorganizing my News SP from last to second to last. EXITthen back in and it stuck. I switched it back to last place and all worked fine. After a whole night of waiting, this morn everything was scheduled correctly and back to normal with Crusoe in my lineup.
