Available Disk Space For Burning DVD's
I'm just learning how to use iMovie and iDVD so you'll have to excuse me is this is an obvious question but I seem to be having a weird issue with the available disk space for burning a DVD. I created my DVD movie with iMovie and saved the 35GB file to my 200GB external firewire drive. Combined with the other stuff on that drive I have 40GB of free space left. As well I have 22GB of free hard drive space on my Mini's 40GB drive. Now when I try to burn the DVD I get a popup message telling me that there is insufficient disk space to burn the DVD. Which disk space is it referring to, my Mini's drive or my external drive? From all the info I've read I thought that all I need was double the DVD space on the startup disk, or about 10GB to burn a DVD. Is this correct? If so, why would it continue to say it's out of disk space?
Cheers
