Guys after reading your responses as I have just purchased a MacBook pro and a Sony dcr-sr68 camcorder, I realized why it wasn't recognizing my cam- I didnt have the cam connected to the charger as well as the computer. If you switch your camera to manual settings, connect via USB AND plug in the ac power, iMovie recognizes your device and you can capture the footage with sound and all. Hope this advice helps whoever else has the same problems with a Sony.
