Hmm for the first question you could use
FairUse Wizard, MeGUI or any other dvd ripping program.
If you're gonna use MeGUI then I suggest you look here for more info on how to do it:

Converting dvd's to mkv's will remove the dvd menu...
For your second question err.... convert the file to mpg using
Any Video Converter Free (or any other program that converts to mpg) and burn it to a dvd. I'm not sure if it'll work though, since I havn't tried it.
