Copying a CD with Nero

Hi, I hope someone here can help me! I use Nero 6, and I’m having trouble copying a CD. It is an enhanced CD that has video clips and things like that on it, and autostarts when you put it in the drive, playing one of the clips. I used Nero’s Copy CD function to try to make a copy of the CD, following the instructions exactly, but when I put the copy in the drive, two instances of the autostart program start up, one a few seconds after the other. You can hear two instances of the same video clip going at once. I can’t figure out what is causing this to happen, but it only happens with the burned CD, not the original one. Can anyone help me? Thanks!
