I don't really know what is going on but if it were my machine, I'd copy the contents of the DVD onto the harddrive and run it from there to side step any DVD driver issues.
It looks like there is some issue with the installation of that one particular file. You do have enough harddrive space to install I'm assuming? I've never found a game more harddisk hungry than UT2004 with a few mods
I've setup the 6 CD version on Linux heaps of times on several distros without issue.
