I find DVDFlick (http://www.dvdflick.net) very good for creating DVDs from video files. It supports loads of video formats/codecs, and is dead simple to use if you just want to burn a single video file to DVD. For more advanced use it has a reasonable amount of more complex functionality including basic support for menus.
Another useful package is Zero Assumption Recovery (http://www.z-a-recovery.com/) - a very powerful tool for recovering deleted files from digital camera cards. The full version (paid for) can do data recovery on hard disks and other media, but recovery from digital camera cards is free.
