When I installed the 10.1.1 update i read something about support for hardware acceleration for external displays for NEW Powerbook G4s.... well after the install when I try to run a TV as my external monitor all I get are squiggly lines on screen. Does anyone know what happened and if there is a way to fix this. I was hoping this update would allow me to watch DVDs on my TV without having to restart and close the laptop... any help would be appreciated...
