I always back up my DVDs and here's two useful tricks I've picked up along the way:
To
edit a DVD (for example strip out trailers or even a chapter/s you don't like), you can use this guide-

-but don't use dvd shrink if it's too big, just use the next guide:
To
split a DVD- I've attached a zipped html file of a now defuct web guide to splitting a dual layer disk onto two single layer ones. Just click on the "18_4" file to open the web page image. If you have an ISO, you need to mount it on a virtual drive like daemon tools before "ripping" it as described in the first step of the guide...
obviously you need various tools; just google for them if the direct links in the guides don't work
Edit: I'll re-up the zip shortly...
Edit2: done...
