Well, I'd say that there are still some bugs to be worked out with the Hopper and how it deals with timers. Check out this picture of my Timers list after I'd been adding some shows to recreate them from my 722 (using the Hopper's Seek and Record, which may or may not be the culprit).
Especially check out the numbers of the timers.
Get working, software engineers!
