Disk Repair can trigger "underlying task" but I've never heard or seen a Permissions Repair do so.
You should never use the DVD to repair permissions. You should be using the same OS version. And of course you can always repair permissions from your boot drive; or from backup/clone or alternate "emergency" drive. Otherwise, the DVD and older version of DU will be wrong.
I know I read that on MacFixit, but I am not sure I bookmarked it.
Don't rely on Apple First Aid, even a clean bill of health doesn't mean there aren't problems which Disk Warrior can deal with.
