Streaming video online has replaced physical media. Not sure what your use case is, but more and more households don’t have a DVD player. The only other alternative is to ditch the idea of burning a DVD at all. So you’ll need one of those third party apps. This is what iDVD did, and what current third-party apps did. A video DVD-brunign app does more than just run the disc, it also formats the video and creates the necessary data for the DVD menu system.
The DVD has to have a specific format and the video itself has to be re-encoded into a very specific format or DVD players, which still operate with standards from the early 1990s, won’t be able to recognize or play the video. You can’t just throw some files on a disc and expect it to work in a DVD player. Video DVDs are very different than data or music DVDs.
