I'm looking for any web pages that have advice on creating DVDs in terms of authoring styles. I'm not looking for technical advice, just how people are laying out their buttons and program flow.

I tried doing some web searches but all I end up with is specific technical details. I'm just trying to get some ideas without sitting down and looking through a bunch of commercial DVDs. People are very creative and willing to share their ideas, so I'm pretty confident the information is out there on what people like to do.
