Hope I'm not asking a question that has been ask many times before...

Being very new to the DVD burning thing I have a question.
I received a new PC for Xmas, and my son hooked me up with DVDFab decrypter. My burner software is Sonic Digital Media Plus V7. I have downloaded a movie and have it stored on my PC in MY Documents. Any tips on how I can use my Sonic software to burn the movie. Should be a course on this stuff...lol

ps: not really sure where in this forum I should post a question like this. thks.
