Rip and burn works fine for audio files, but you need valid licenses that allow you to play your copy-protected files anyway.

Even if you don't have a CD/DVD burner you can use rip/burn technique even without Note Burner:

• Create an Audio CD from music files
• Then instead of burning them to a blank CD, save a CD image to you hard drive.
• Mount the CD Image with software like freeware Daemon Tools. It will look like you have a CD Drive with an Audio CD in it.
• Rip music files from your Audio CD
• Unmount the CD Image and delete the CD Image file.

As for M4V files, I repeat, you need valid licenses that allow you to play the video files to be able to remove DRM protection from the.
