If you don’t have a Blu Ray player, you can use your computer to play the Blu Ray ISO.
You would have to “mount” the ISO file, make that file into a virtual (disc) drive. If you have Windows 8 or higher, you can simply right-click on the mouse, and select “Mount.” Otherwise, you would have to download a free third-party software, like Virtual Clone Drive, and do the same thing. Either method you use, you can access the m2ts files—play, copy, etc. To un ”mount” the file, right-click the mouse and select, “Eject.”
If your computer has a HDMI output port, you can play the ISO through your computer and send the signal to your TV.
