I'm skeptical that the Ouya will be able to decode h.264 Level 4.1 (up to 50 Mbps). Xbox 360 can only handle up to 10Mbps peak of Level 4.1. Thus, the only solution is to transcode to MPEG-2 using something like PS3 Media Server. A 100mbit connection is insufficient for high-quality transcoded MPEG-2 in my experience
