Another option is to upload them to YouTube but make the videos Unlisted. You'll need to copy the URLs of each video and send them out to everyone on your list because nobody can watch them unless they have that exact web address. The videos aren't listed and can't be found through searching on Google or YT, so they're reasonably safe from prying eyes.
You can also put them all on an unlisted playlist and just send that out to your peeps, and a nice the nice thing is that you can add new videos to the playlist all the time and your family and friends will be able to watch them as soon as you upload them.
Benefits are no physical media to buy/distrubute/maintain, and some pretty decent future proofing given that online streaming will likely remain a viable delivery method for a long time - or at least would seem to be a primne candiate for being upgraded to the next gen system.
Very few rights or wrongs here (besides the disc issues JL_JL pointed out), so maybe try out a couple options first before committing to any one approach.
