DVD/CD duplicator not burning DVD's.?

I have a megalynx duplicator. It will not burn DVD's anymore, only Cd's. It did at first, but now it keeps saying, "Source not found". Is it the duplicator card that has gone out? If you know where I can troubleshoot this or tech support. Please Help.

10 points, best answer!!!

I don't think one PC has the bandwidth to do all that at once. Do you have a classroom full of them?
