This may or may not be a related problem, but I just found out that my Hopper missed this year's entire season of "Oddities" on The Science Channel when they apparently ran all of them last Sunday and it only recorded four of them. Since I have all my timers set to start a minute early, I saw material that I didn't recognize at the end of the previous episode before two of them, and when I pushed the Info button to see what was listed for an air date, they all had original air dates from whenever they apparently ran them earlier this spring. So whenever they were on originally, either they weren't listed as new then, or they fell victim to the "cancelled by user" bug if it was active back that far back. But I don't think it was active that far back, plus I've never seen it hit every episode of a series.
(Mind you, I can't confirm that they were actually aired sequentially earlier, versus all being aired last Sunday with wrong dates, because The Science Channel's website doesn't list any episodes from 2014 at all!)
