I've installed linux MCE from DVD 0710 onto a core machine and have the MD in a machine with an Iwill KK266 motherboard and a Nvidia GEForce 8400GS PCI graphic card. In the UI1 mode, videos played just fine. Then I got to playing around trying to get UI2 to work by updating the Nvidia drivers. Now I'm at the point where the MD boots up in UI1 and when I try to play either a video from the DVD drive in my MD or a video from the core, the video never starts and the MD goes back to the main screen window after a few seconds.
Does anyone know if this can be fixed or do I need to start over?
