I'm using Nero Burning Rom 6.0.0.19 on XP Pro. When I try to burn a dvd data disk (mpg and avi files) and set the number of copies to 2 the second disk (but not the first) is a coaster. This has happened two or three times now. I'm using Ridata G04 disks. I have checked the "verify data" box and Nero says the disk is ok. The data may be ok, but neither my computer nor my standalone dvd player recognizes the second disk. Anybody else had this problem or know of a fix aside from setting the number of copies to 1 and doing that 2 times?
