There is a better way to backup Unreal Tournament - DVD.
1. Create a Temp-Folder on your HD.
2. Copy all files (& folders) from the DVD to this Temp-Folder.
3. Add a folder "Update" to the Temp-Folder.
4. Download the latest official update from
www.atari.com .
5. Copy the downloaded Update to the "Update"-Folder.
6. Burn the contents of the Temp-Folder to a DVD-R (or DVD+R).
7. Install the game from your backup DVD.
8. Install the Update from the "Update"-Folder from your backup DVD.
9. Play the game without DVD in your DVD-Rom.
(The official Update removes the copy protection !!!)
