Free DVD authoring software is hard to come by. Many of the FREE apps are buggy. SoThink Movie DVD Maker is among the best of the free solutions available for DVD authoring. The app converts most formats, including AVI, MPEG, WMV, MP4, RMVB, MOV, and 3GP to DVD. Basic video editing features like trimming clips and combining smaller clips into a larger movie are also supported. When your video is ready for DVD you can burn straight to disk. The default video format is PAL, so if you are authoring home movies created in the US, you’ll need to change the defaults for NTSC support. This is especially useful in combination with something like Windows Movie Maker for Windows XP, which includes no DVD burning support. While the app will work with Vista, the Vista DVD Maker application has a better burning engine and far more features for authoring DVDs. Check it out!
