What is the best program to compress a DVD9 to a DVD5? I know that DVD Shrink (which is an awesome program by the way) can do this, but I'm looking for the best output possible. I want to backup "Pirates of the Caribbean" whose running time is 143 mins. If recording onto a DVDR which can optimally hold 120 minutes of video; how much quality will actually be lost with the additional 23 minutes? Will the loss be apparently visible? I will be putting only one audio track and removing all menus, subtitles, etc. Will I actually be better of splitting into two DVDR's?
