I'd free up at least 4 times the size of a full DVD disk you are trying to create. That's been my experience and why I leave C drives to be as big as possible so I never see this issue.
I used Click-to-DVD software on my Sony Vaio (Windows XP) for over a year. The results were excellent. Recently, after capturing the home videos, the software converted video and audio in MPEG but got stuck while creating the DVD image on Hardisk.
I?ve uninstalled - reinstalled the software a couple of times. Made sure there is over 5 GB hard disk space on C: and 50+ GB on D-drive. D drive is where the temporary files are created.
Please help. Sony Vaio support was useless.
Thanks in advance,
