Yes you can, but only with the right software. DVD's can handle both audio and video so no need to return them. However, if you don't have the right software, then you can't burn music on to it. There are good softwares out there like Roxio's Easy Media Creator 10 Suite (
http://www.my-linker.com/hop/roxioeasymediacre ator10suite/) that will easily create DVDs that can play up to 50 Hours of music. Some third party softwares also provide this, but they are slow and unreliable. I would give a little more to get Roxio Easy Media Creator 10 b/c you will thank yourself when it finishes burning your DVD in half the time.
