Hmmm. I rip my blurays 720p H.264 video, and 5.1 AAC audio and it streams just fine to my PS3 in 5.1. For me there is no reason to rip to and MKV when MP4 uses the same video codec and no reason to use ac3 or DTS audio when 5.1 aac is basically the same and is compatible on nearly all devices which MKVs aren't.
