DVDStyler 2.9 just came out. It is not ready for prime time. DON'T DOWNLOAD IT! They broke the transcoding function. It spins its wheels forever, producing thousands upon thousands of "buffer underflow" messages.
This 3-star review is for DVDStyler 2.8.1. As a freebie low-end DVD creator, it can't be beat. It can produce a 3-hour DVD in less than 30 minutes. If you want more sophisticated features in your DVD, you must tinker with the dvd.dvds file, not very easy but learnable.
One warning though: If you want to change the menu font settings, this application will crash every time. This bug never seems to get fixed, and it probably has something to do with cross- compiling the application for Windows/Linux/OS X. You can change the menu fonts by tinkering with the aforementioned dvd.dvds file.
