I recently looked into this issue for a DVD I was distributing. It is my understanding that indeed these particular DVD logos are copyrighted (note the TM). I was told by my duplicator that you can only use these logos if you are replicating your DVD’s through a licensed duplication facility that has paid a fee to the company that owns those particular logos.
I was advised you can use the words DVD Video or Video DVD in a different font variation and layout, and without their little disc graphic. In other words, just make up your own logo as long as it is different.
