Ive tried everything to get XBMC to stream but it has severe buffering problems. Tried it wirelessly using SMB with Windows 7 and also tried ethernet. Turned off hardware acceleration. Tried hooking up my external drive to my AEBS but still buffers. iTunes plays perfect and rented movies stream flawlessly and Netflix streams flawlessly so really dont think its my network. Mp4's work ok still have some sound and buffer issues but most of my movies are in Video_TS format and they buffer so bad its unwatchable. Running the latest Apple TV 2 4.3 firmware created by season pass and XBMC 10.0.7. Any ideas what I can do or is this just a beta problem?
