You'll find a description of the MPEG-2 container formats (Transport and Program Streams) in http://www.opennet.ru/docs/formats/mpeg-cd.doc, for example (Beware! It's an MS Word document!). It's only a draft but it's pretty accurate. DVDs usually contain Program Streams, but due to limitations of the file system (ISO 9660) they're chopped into 1GB pieces called VOBs (Video OBjects). Each VOB includes one or more VOBUs (VOB Units?), as far as I remember, which in turn contains special sectors for easy navigation (to be used by dumb DVD players) along with the MPEG audio and video streams. I'm still looking for implementation details about the nav sectors, so if anybody can give me a hint...
