can I play a mini-DVD on my MacBook?

I would not risk doing this. I've seen other threads on here where people have put mini-CDs into their MacBooks and have had trouble getting them back out again. (At least, not without the help of tweezers.) I'd just try to use an external player or, at the least, hook up your camcorder to the computer via FireWire.

Leslye,

I also have a mini-DVD camcorder, the Sony Handycam, and the slot-load drives will NOT take a mini-disc.

Fortunately, the camcorder itself is recognized as an external DVD-RW drive. So I can play the discs directly off the camera. I would imagine any USB or Firewire DVD camcorder would be recognized similarly.

no, i dont think that would be a good idea, if you had an external tray drive that would work though.

I'm pretty sure it says specifically in the little instruction book that comes with your Macbook that you are NOT supposed to do that. The disk can easily get trapped in the drive.
