the version of twoky that is included int he latest firmware version CANNOT stream MVK's of any kind to the PS3. The solution tha tI have foudn is to use a computer with Ps3 media server (google it), to do this. I can tell you that this solution works and this is what I use to stream 720p and 1080p anime to my ps3.
