Re-Imagining Episodic DVDs

I have a bunch of episodic dvd sets (Band of Brothers, Horatio Hornblower, etc). I want to create new DVDs from those originals that eliminate the credits and such in the hopes of a) reducing the number of DVDs needed to contain the entire set and b) making my viewing time more efficient.

How would I go about doing that, and do you think it would be worth the time to do?
