If you have a DVD with multiple TV episodes and you are wanting to maintain a VOB or ISO format, find out how many episodes are on the DVD and put a hyphen between the episode names. Eg,
\The Man Show (1999)\The Man Show S01E01-E02-E03-E04\(your VIDEO and VTS files)
This will create individual files with the name of the episode in your TV SHOWS main menu item, but of course when you open them it will play the DVD containing that episode (along with any other episodes on that DVD)
