The problem right now is that there is no such "unique format". Everything has its drawbacks, and this why html (I do not like it that much either overall) or rtf (if you are willing to forgo some stuff like pictures, maps...) are needed since you know you will be able to access your books later.
Regarding dvd burning try the free software (cdburner xp 3 - there is new version 4 using .net 3, but if you do not want to bother with that, version 3 will do nicely) and you will see how much it improves your experience.
