Re-encoding parts of a dvd say just the credits?

[qwik3r2]

Ok trying to save as much quality as possible on a dvd so it will fit on a single disc, so removing all the extras with dvdremake, dvd shrink and menushrink, than more than likely burning with clonedvd2, but i was thinking what if i encoded every dvd's credits (which are usually fairly large) with a low bit rate to save quality on the main movie, sure it would take a while but how do i do it?

I am thinking demux the movie (don't even know how to do that) than use some sort of mpg editor and CUT the credits than encode them to ? than mux everything back together than convert from mpg to video_ts

Sound feesable? If so what programs shall i use? Thanks.
