Hi gadgetmax, I noticed the same problem as well. I tested on an Apple TV 2 and 3, across iPads and iPhones, and no luck finding a workaround. I checked the Asset Guide and noticed it was updated to 5.1. I made the revisions to my epub and tried again but still no luck. Apple also updated their Fixed Layout Example to 3.0 but again that also exhibits the same issue. I'm guessing we'll just have to wait until Apple fixes this bug in iBooks. If you find anything else I would love to hear it.
