I always keep a smaller divx or xvid encode of dvds on hand on external hard disks. Easier if I still want to watch something without taking out the dvd. At the end of the Diamond DVD I had trouble getting it ripped right. Every so-and-so seconds the audio would glitch. Perhaps it’s the program I used, but I don’t understand since it did the rest correctly. Extra protection? Who knows. I just did it in a different way now, by using DVD2AVI with Decode/ Dolby Surround Downmix as explained in this guide.
Before that I installed graphedit again, registered a couple of filters. After that my mpg’s wouldn’t play anymore so I had to unregister all filters. >.< Thankfully I noticed it now instead of a week later because I wouldn’t be able to trace it back to the filter installation.
