It has been a good while since I burned anything on a Mac - so this is mainly from memory…
Toast, Burn, Disco, and iDVD were all pretty good and easy ways of burning DVDs, IIRC. Hopefully they are all still obtainable and work okay.
www.videohelp.com used to be really useful site for finding this kind of info - it may be worth checking out for more advice and up-to-date suggestions for software. 👍
Re Harmy’s Despecialized Edits - it’d be a pity to compress them to fit a DVDs. Would it be better to simply buy a portable USB drive and keep them on there? Evan a decent branded 128gb USB drive only costs ~£10 (and you’ll be able to put a lot more other content on there too).
Whatever you decide, please let us know how you get on with using any of the above software (or any other software you may end use using to burn to a DVD). 👍
Good luck with it!
