Hi, i have the same problem. Before upgrading to 7.8 i could stream to the phone using windows media player 12 as dlna server. wmp12 has the capability to transcode on the fly to the phone, but not the capability to pre-transcode file....using another dlna server, kooraroo, which has the capability to pretranscode files i can see them again, but only after pre-transcoding....Let me know if you obtain other informations.....
