This is the same version given away a last year, and an existing copy from last year can be renewed with the key in the readme.txt file. Maybe the best thing about ThunderSoft Blu-ray Ripper is it's easy to get rid of, with files in the program's folder, and in the added folder: Users\ [UserName\ AppData\Roaming\ts_bd_converter. An empty folder's added in My Documents, and the registry gets a Thundersoft key & a key for uninstall: [HKLM\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Uninstall\ {31A53A41-272A-4531-B72C-BC6B0CE32FD9}_is1]
A Blu-ray disk has multiple .m2ts files which contain 1 video stream, and optionally one or more audio & subtitle streams. DRM can split the video titles across multiple .m2ts files, and a playlist tells the player which .m2ts files to play and in what order. SO far so good, except DRM does a good job of hiding the correct playlist -- there can be several fakes.
That means that if you go to the store and buy a movie Blu-ray disc you need either a software or hardware Blu-ray player to decipher everything, find the correct playlist, and then play the video files in the correct order. If you bypass the DRM *And* determine the correct playlist, then an app like the free tsMuxeR can create a new Blu-ray layout in a folder with a single .m2ts file [if there were multiple files they'll be joined together] and a single, simple playlist. That .m2ts file is compatible with many more players than the MKV or .mp4 video formats, and the structure's there to simplify playback in a Blu-ray player [software or hardware]. Again, the hard part is finding the correct playlist so the video files can be joined *if* needed. Putting the same video in a MKV or .mp4 container doesn't do you much good overall.
Since ThunderSoft Blu-ray Ripper cannot handle the DRM part -- it failed to read 3 Blu-ray discs that another app was able to copy just fine, so the discs were good -- there really is no use for the software.
