Cropping for DVD TV

Because of the size of the pictures not being close to a T.V. 4:3 aspect ratio the pictures have black side bars when viewing them. I was wondering if anyone knows a way to resize the background wider to match the 4:3 ratio?

DVD Menu Design: The Failures of Web Design Recreated Yet Again

Designers of DVDs have failed to profit from the lessons of previous media: Computer Software, Internet web pages, and even WAP phones. As a result, the DVD menu structure is getting more and more baroque, less and less usable, less pleasurable, less effective. It is time to take DVD design as seriously as we do web design. The field needs some discipline some attention to the User Experience, concern about accessibility for those with less than perfect sight and hearing, and some standardization of control and display formats.

Exporting to QuickTime or for use with iDVD

You have this great project that you've just finished, and you need to bring it into another program, display it on your web site, or turn it in on CD or DVD. To do this, you will need to export your movie. iMovie has several 'built-in' configurations that take much of the guesswork out of compressing your video for optimal playback on one of those media types. I often find, however, that the standard choices are not quite what I want or need. This is when the Expert options come into play.
