Hi. I have no access to a DVD writer yet, but am trying to prepare a whole heap of content for later authoring. Currently I am just creating single DVD compliant MPEG2 files.

What are the requirements for creating chapters? Do I need to have separate files (I don't currently think so)? Do I need to make sure that I have a GOP header at the places I want to have chapters?

How are still frames specified (that is, at the end of a chapter or something to hold a frame for say 5 seconds - and yes, it can be done by the spec before you say I can't)? Do they have to occur at the end of a VOBU or a VOBS? And are you able to use subpictures to do fades (ie. is there an alpha channel component to the subpictures)?

I'll keep reading DVD Demystified and see if I can figure out some of these questions.

Thanks for the help
