iDVD 7.1.1 is a 34MB update that improves stability and brings compatibility for sending slideshows from iPhoto ’11 to iDVD. Though this update targets an issue relating to iPhoto ’11, Apple recommends it for all users of iDVD 7, which was bundled with iLife ’09 and iLife ’08.
Both updates are available via the support pages linked above, but they should also be waiting in Software Update.
