Starforce... blah. I never buy games with such horrible copy protection. It's one thing for a company to protect their work, it's another to do it at the expense of the customers hardware.. that protection can damage your cd rom drives after a while.
On an on topic note, I believe you can copy all the installation files from the 6 UT04 install CDs and put them on one dvd and not have issues.. just put them each in their own folders on the dvd I believe.
