I used a free download called WinX DVD author. I'm horrible at tech stuff, but it burned my DVDs quickly and did everything for me... it was just a few steps and very intuitive. It does have to be a DVD (rather than CD). My DVDs were R/W (read/write), but I'm not sure that that was necessary... it's just all that I had. lol I prefer DVDs for many reasons, but one is because I'm very visual, and the covers help "trigger" my memory of the actual workout more than the title does. I printed pics for each of the downloads from the pics Cathe used to announce each one. I printed the time and description too, and poked them into the covers I provided for the DVDs (as well as handwrote the # that proves I obtained them legally on each one). lol When I donated a bunch of DVDs (other instructors) that I just didn't enjoy, I kept the cases, and slipped the DVDs into CD cases. That way, the donated workouts will still protected, but the ones I put on DVD were in the same size case as the rest of my collection, and able to be labelled and organized in a similar manner. I tried using Windows Media to burn the downloads, but was not successful. Like I said... I'm not great with tech stuff, so it could have been user error. lol My computer was also becoming more and more uncooperative after my Windows 10 expired, and pretty much crashed when I attempted to do the Windows 11 update, so... that could have contributed to the issue. WinX DVD, though? I had no problems. So, if you can't get it done with Windows Media, try WinX DVD.
