I am having a difficult time trying to burn dvds on my laptop. All of the videos I want to burn to a dvd were downloaded with RealPlayer video converter. From there I just can't figure out what to do. Somehow I always get the files onto the dvd but it won't play on the dvd player! Should I download a dvd burner from online? Or should I move the files from RealPlayer to windows media player or some other program? I need a detailed explanation with step by step instructions pleeeease! =) Oh, I have a Dell Inspiron 1545 with Windows Vista home basic edition
I've downloaded DVD Flick and every time I click add title to begin the process of burning the dvd it says the file might be corrupted or it's format may be unsupported. Now what do I do?

As I said before all of my files were downloaded using real player video converter. Either from youtube or some other sight on the internet via internet explore. Don't know if this makes a difference or not
