My setup used to work but now any attempt to display video with the extender produces a 000-0904 error and hangs the PC. It takes a POR on the PC to recover. It plays Music & displays pics OK but I can't do video with the extender. Media Center video is OK on the PC. - I reset the extender and reran setup - tried both wired and wireless connections - killed all startup programs with MSCONFIG - Tried connecting through a different router/switch The symptoms remain unchanged. Anyone have any ideas?
