I lost the track of which patch goes where :) If you're a lucky owner of an LCD on your bb-xM;) you might be able to do something similar, to what's described here http://download.open-technology.de/BeagleBoard_xM-MT9P031/BBxM-MT9P031.txt but both yavta and mplayer on the board, while short-circuiting the network;) I.e., pipe yavta output directly to mplayer.
