Try rendering or burning the m2ts file to a re-writable disc first.
Then ripping the disc back to your HD in ISO format.
ISO files are generated when you copy or rip a CD or DVD from your CD/DVD drive to your computer Hard drive.
Not sure if there is a quicker way since I am not familiar with the copy protection software you are using.
