Apple has released a couple of updates today, for iDVD and for the MacBook Air. The update to iDVD brings the version to 7.1.1 and fixes problems users have had with sending iPhoto '11 slideshows to iDVD. It also fixes some stability bugs in the program. The software update for the MacBook Air (late 2010 model) addresses a problem in which the systems would not go to sleep.
The updates should be available via Software Update, but can also be downloaded from the following locations:
The iDVD update is 34.53MB in size and requires OS X 10.6.6 or later, and the MacBook Air update is 342KB in size and requires OS X 10.6.5 or later. Be sure to back up your systems using Time Machine or another full-system backup option before applying these updates.
