Nero 7 - DVD Burning Problem, HELP?

[Embryoyo]

I'm trying to burn a DVD with a menu for my girlfriend, but it keeps giving me an error before it even starts burning the content onto the DVD...
I'm using NERO 7 ULTRA EDITION - NERO VISION "MAKE YOUR OWN DVD-Video".
I have added the log file from my last attempt to an attachment to this thread, but I have no idea what any of it means...
Can anyone help me? THANKS so very much if so!!!
