DVD Flick is an open source Windows program that allows you to burn various video file types to DVD (as an actual DVD, not as a data file).
It's fairly simple to use, but there are a couple of weird nuances:
- By default, it doesn't actually burn to disc when you create the DVD. It creates a DVD-ready set of files in a folder on your computer. In order to actually make the DVD, you have to change the settings in your project by going to Project Settings > Burning > Burn project to disc.
- Also by default, there is a weird audio delay (similar to bad dubbing on Bruce Lee movies from the 70s). In order to get rid of that delay, you have to go to Edit title... > Audio tracks > Edit > Ignore audio delay for this track.
