codec overrun
This happens both when opening from within disk utility (which produces the message "Unable to attach disk0.dmg - codec overrun"), and also when double-clicking the DMG file and invoking diskimagemounter (which says "the following disk images failed to mount... " and also cites "codec error"),
I've searched the forums for "codec overrun" and see all kinds of messages about firewalls and bad network configurations. But has nothing to do with my network (and the same problems happen when I am totally disconnected from a network). I'm doing this using a firewire cable to a portable drive. I'm not downloading any DMG files from anywhere.
Help?
