I just found an article on what the apple tv's limits are for those two settings and that may have been my problem.
I'm not an encoding expert, but the presets for AppleTV in the current version of Handbrake produce what I would consider to be very acceptable results.

I think the AppleTV can be picky about bitrate because if you are running up around the upper limit of what the ATV can handle (5 megabits), a scene with lots of movement or shift in detail can temporarily cause a spike above your average bitrate, and the ATV with its limited processing power is not going to be able to handle it gracefully.

I don't really see much benefit visually to going above 2500 kilobits, for 720p content. If you need or want better visual acuity than that, you are probably better served with Bluray or a higher performance HTPC setup, I think. (not to mention that streaming, rewinding and fast forwarding, are all pretty painful with high bit rate stuff on ATV)
