On very rare occasions, when someone asks me to burn videos on DVD-Rs, I dig my iDVD and have some fun reminiscing the old days. Fun fact: it hasn't been 8 years since we were still burning DVDs for everyone. Although I could deliver video projects using MegaUpload (remember that?), people would still ask for DVDs. Anyway, if you don't wanna buy and old iLife suite, I'd tell you to consider paying for the software Vuze. It's a p2p program that also offers DVD burning and some other stuff. I use it to stream videos to my TVs wirelessly. I really like it given that I do not own an Apple TV. If you want something free, Burn is the best option I think. But be prepared to work on very simple DVD authoring options.
