Need Help In Nero Express 3!

Please help!
I’m not an export in nero express 3. I’m using it to make DVDs.
I download files from Emule and then make my DVD’s. So far, everything went well except one file I have a problem with. For some reasons a burning process stops at the middle and stays fozen. I’ve tried many times burning this file and every time it does the same thing. When I click on ABORT, it doesn’t abort it. Any help?

I’m burning avi files to DVD + R format.

Thanks a lot It looks like this ( see attached file)
