I was wondering if it might be some hack to use the media mail USPS rates, but looking at them it doesn’t seem like it would work.

That’s a legit reuse move. No new materials produced to be discarded, and if the recipient doesn’t want the DVD, they can donate it rather than sending it to a landfill.

One of the things I find interesting on the Internet is how often people’s first reaction to a thing is to take a photo and post it. It provides good content sometimes (like this one is funny) but I’ve just never thought like that
