Just a quick update - I confirmed that it is definitely PTAT that is the problem. If I disable PTAT, and then check the timer schedule, the recordings show up correctly. Re-enable it, and they show up as skipped. Oh, and I have two Hoppers, and both do the same thing (although I don't normally have PTAT enabled on the second Hopper).
Sorry if this seems like a dumb question... but isn't this how PTAT is supposed to work?
If you enable PTAT, then timers set for PrimeTime LiLs should be skipped UNLESS you specifically mark that you want to save them... IF you had done this before, maybe the glitch is that S221 undid your setting to override PTAT on the timers?
Also, out of curiosity... I've seen some screens that look like IF you have some things recorded via PTAT that there is a "Save" and a "Save series" option... is it possible that IF you let PTAT record a show, like Grimm, then on that recording choose "Save series" instead of setting a timer that it will do what you wanted it to do?
On a semi-related note... NBC sometimes has their shows in the On Demand section, and usually free when they are... so you might want to check there for the episode that you missed that was already deleted.
