Weba google hit on apple's site says current apple gear supports: H.264 Baseline Level 3.0, Baseline Level 3.1, Main Level 3.1, and High Profile Level 4.1. The problem wasn't baseline vs. main, it was the level. 5.1 is HUGE bitrate/rez, no idea why your tiny low bitrate video would have its headers saying it required a level5.1 decoder. The H.264 specification includes two types of parameter sets: Sequence Parameter Set (SPS) and Picture Parameter Set (PPS). An active sequence parameter set remains unchanged throughout a coded video sequence, and an active picture parameter set remains unchanged within a coded picture.

WebJul 12, 2010 · A movie with L4.1 could allow higher bitrates than L4.0 (but it still doesnt say anything about the actual quality).
