I am really frustrated about iMovie and GarageBand '06. iMovie is extremely unstable and often freezes, and GarageBand will not let me hear ANYTHING! I press play to hear what I have done and I get nothing. I am using it with the mini in my sig, so the freezing should not be due to RAM. The files I'm accessing in iMovie are on an external FireWire hard drive thats faster that the mini's internal one.
