DVD to mpeg, is it possible

[kumnio]

Hi probably another stupid question from me, but

is there a utility that allows for a disk with several episodes on it to be saved on a hard drive as an mpeg, either version.

I guess that its mostly americans on here, so an example would be the west wing, with 4 episodes on each disk, could I save them as 1.mpg, 2.mpg, 3.mpg and 4.mpg.

thanks again if anyone can help me out
