I'm getting an external HD to use for capture with Vegas 4.0 . Is the 4G file size limitation of FAT32 a problem for video capture purposes? Also, even though I don't have a Mac right now I'd like to be able to use the external disk with a Mac (and probably be able to use captured video on the Mac with iMovie or FCP).  I know Macs can see FAT32 and not NTFS. However, I know there are utilities available to allow a Mac formatted disk to be seen by Windows - would that be a better way to go than either FAT32 or NTFS?
