It sounds like you want to make backups to optical disks, and not to a hard drive. For that process I recommend BD Rebuilder and ClownBD, depending on the size of the original movie and whether you are doing a complete backup or movie only.
BD Rebuilder can make a complete backup, or movie only backup and compress the video to fit a 25gb disk. The quality will be quite good, indistinguishable from the original when playing back the video. I suggest reading the guide linked in my signature for BD Rebuilder. It is a free program.
ClownBD isn’t strictly necessary, but I use it on occasion when I want to select just the main movie [B]and[/B] the main movie will fit onto a 25gb disk without compression. Sometimes the main movie is split into several different m2ts files, and ClownBD is a good way to put them together.
If you are willing to make full backups to 50gb disks, you don’t need either of those two programs. All you need is AnyDVD HD and ImgBurn. Decrypt with AnyDVD HD and use the built in ripper to put the entire movie on the hard drive as an ISO. Then burn with ImgBurn to a DL 50gb blu ray disk. The only problem is the cost of the blank 50gb disks…which can be as much as many commercially made blu ray movies! Not many people choose to do this.
By the way, I recommend decrypting and ripping the entire movie to the hard drive first, no matter which program you use to work with the movie. AnyDVD HD can rip as files, or as an ISO. If you are going to upgrade AnyDVD, I suggest doing so before the 1st of January. The lifetime updates will no longer be available after that date for new purchases or upgrades.
ImgBurn is the program of choice when burning blu ray video. Use UDF 2.5 setting…the program will prompt you to use this if you have it set wrong.
You’ll need PowerDVD to play back your movies on the computer. It won’t do anything else. If you decide to play movies from the hard drive, you should rip them as ISO files, then mount in the free program from Slysoft called VirtualClone Drive. You can also work with them when mounted in this virtual drive.
