DVD Xcopy exits after reading dvd

I don’t have all of the hw specs with me, but I’m running windows xp on an Amd Athalon XP Processor with a gigabyte mobo (nvidia chipset), a gig of ram, and an nvidia 5200 fx video card. I believe I have a Samsung DVD burner. My problem is as follows. Xcopy platinum sees my dvd recorder, reads the entire movie in, then exits for no apparent reason. There are no error messages whatsoever, the software just closes itself. I’ve tried three different DVD’s (in an attempt to burn) to no avail. Any help would be appreciated. Thanks,
