compressing or combining .bup .vob and .ifo

[scootervon]

Hello i have a bunch of movies that were changed into these 3 types, ive figured out how to get them to play but is there a way to compress/combine it into 1 easy to use file, continue to have them working menu's and what not. 2nd maybe make them smaller so they take up less space on the HDD. more over if possible an all in 1 program would be ideal so then i can put it on a readable file for either ipod or dvd burning use
