Too help you understand about the various formats (better than I could manage, clearly anyway), have a read of the following link, it breaks down each format and explains them a bit, hopefully between that and this it will help answer your question.
Audio file format

http://www.fileinfo....filetypes/video (great list with a good break down, but don't get bogged down understanding the lesser known formats, they tell you the most common ones)
DVD-Video is another read to aid explaining about this, and also mentions audio within this format, it would appear that what the DVD contains greatly depends on how it is made, eg if a bought DVD was capable of utilising Dolby 5.1 or similar, then the format used on that disk may differ from that used on a disk that did not have 5.1 ability, again no clear answer I'm afraid, there are just so many variables, but I hope these links help clear this up a bit for you.
This Link may help you gain a much deeper understanding on how big a field this is, hence not being able to have conclusive answers, and it gives a reasonable breakdown on each format, and touches on compression when relevant, so it may help you more.
As too audio DVDs, these are most likely to be in .mp3 format, simply because any device that can play audio DVDs are most likely to be using this format, the average CD player wont be able to handle an audio DVD AFAIK, but there may be exceptions, but this is the most common format used here.
You can create VCD's (Video Cd's), most common use of these is converting a home shot video of say a birthday or the like, and burning it too disk for other family members to be able to enjoy it as well, ideal for shorter video's rather than a full DVD, hopefully This will explain a bit more for you here.
Video compression will tell you more than I am able too here, it's a very complex area depending on what you want to do with such info.
I'm sorry I don't know enough to explain clearer than I have, but hopefully between this and putting all the links together between them you should hopefully get at least some of the answers you need\want.
