In my previous post i asked the following:
What is the movie file size in MB and what format is it (ie What's the file extension)?
Please complete your system specs, follow this tutorial: System Info - See Your System Specs Must have details of your DVD/CD writer to answer your question properly!
You have given the file extension but seem to have ignored everything else.
I cannot help you unless you answer these questions!
BTW when you signed up for your You Tube account you agreed to abide by the You Tube Terms and Conditions one of which clearly states that you must not copy (download) any You Tube content. You seemed to have ignored this as well!
While I am asking questions here's another couple:
Do you intend playing the finished video in a DVD player or through your PC?
How did you try to burn the movie, did you choose to burn a DVD or a data Disc?
