You know how you got to rename and you can change like .mp4 or .avi can you change blue-ray format to .mp4 or .avi format so you can like burn it to a disc but still the same awesome quality or not?
I would suggest finding a blur-ray DVD ripper program. There's one online that costs $40 or a little more, but you need a blue-ray DVD drive, or it will not work. If you use this program, you can choose either mp4, AVI, WMV, etc.
