    I just connected my MacBook to an HDTV using the mini DVI -> DVI cable, and then the DVI -> HDMI cable, but I can't do anything from there. An input channel shows up on the TV, and then it displays my desktop picture (no icons), but I can't get anything else to show. I'm trying to play an .avi file stored on my hard drive. Any clues?

    You need to mirror your desktop, not extend it.

    System Preferences > Displays

    If you mirror doesn't it use the lower resolution? If you use an extended desktop you can set the TV to use its full resolution if it is 1080p (if it is 720 than mirroring should be fine.)

    If you do use extended desktop you just drag windows off the side of your macbook screen and they will show up on the TV. You can also change which screen is the main display (The one with the dock and menu bar)

    If you have an external mouse and keyboard, you can close your computer. Then the videocard will be dedicated to your external monitor (TV). Just make sure in your system preferences that you select to allow BT to awake the computer.
