Depending your project size, 30 minutes video project can use 1 hour to create the file and burn it on a good computer. If your computer is slow may be 4 to 6 hours rendering time etc... Try to burn about 10 minutes on a DVD but Blu-Ray file. A DVD can give 30 minutes in Blu-Mode mode and remember a B-R file need a B-R reader to play on TV.
