I was actually researching a very similar problem earlier today. I have a bunch of copies of DVDs that I own, and made in Linux using a combination of xine & dd, xine to grab the css keys, and dd to copy /dev/hdd. I lost one of my original DVDs and wanted to burn the DVD image to a new DVD-R DL so I can play it on a regular DVD player. Of course I realized too late that the CSS keys weren't copied with the rest of the title, and after many discussions and searches have found that what I'm now looking for is a CLI tool for removing region encoding, CSS, and disabled user options. I haven't found anything yet but I'm looking into the options DVD::RIP provide. Does anyone else have any software we can look at for removing these hindrances from our DVD images while leaving the actual content unmolested and suitable for burning as an iso back onto a DVD disc?

I guess I am achievement whoring then, because I can't let April 1st pass by without actually getting anything out of the deal, right? So here goes, please no-one mod me, I just want to disappear into the background! At least this is better than ponies, I still suffer from partial blindness in my left eye when I accidentally looked at Slashdot in the ponies theme before I turned away.
