That's a work-around and may be acceptable in this case, but it's disconcerting that you couldn't loop smoothly w/one of the other suggestions. :(
Hey gang, this turned out to be the best solution (I tried all your suggestions): I made the loop 1 minute long (6 iterations), with an even number of frames at 30 FPS. My H264 still appears to repeat a frame or stutter at the loop point, but you'd have to be really focused on it to spot it.
Thanks for all your valuable input.

In my experience, players are more likely to hiccup when they loop (seek) than when they are playing. To reduce the chance of seeing this hiccup, you deliver a longer stringout of back-to-back 10s loops. This was necessary in the olden days of DVD (to accommodate the drive's seek time), but it may still be a reasonable method today (depending on your player).
Since you have an odd number of frames, you could also implement Rick's interesting suggestion of matching your number of frames to the compression cadence by adding to a stringout, instead of going back to the drawing board.
