brother esau, it really is an easy process, virtually self-explanatory if you just explore the programs. DVDFab HD Decrypter can rip the entire movie. Put a commercial dvd in the drive and open the program. Your dvd should show up in the source. The mode you use is Full Disk. Now pick a target by clicking on the folder icon next to the target line. I usually make a new directory on one of my hard drives using the name of the movie. Start the ripping process. This will give you the whole movie in file mode, uncompressed, in your target directory.
To view it in PowerDVD, start PowerDVD, then hit the small icon that looks like a dvd drive at the bottom of the window (or hit Control O). This will give you a drop down box with several options, including Open Movie File on Hard Disk Drive. Navigate to the directory and click on it, then hit ok.
