There is now a handy new tool that you can use to convert those flv files and burn them onto a DVD, it's called Replay Converter. As the start the program up you'll see a button that says 'add file'. Using this you can add files to the program's queue. Put a blank DVD into your DVD burner beforehand. Now with the files in the queue, tick the 'Burn to CD/DVD' option.
