One possibility that might solve your problem is to get a Plextor burner that also includes Plextools Professional, as under that you could use the "Gigarec" function to test your cd-r to see how much it could be 'overburned.' Also, while it could solve that issue, it might not be the cheapest way, either. Anyway, the Gigarec function would let you overburn a disc (depending on how good the test results are) and record the information you need on it. However, while that disc may be fine on a Plextor burner in your computer, it is not guaranteed to play in other computer drives. That's the best I can do... hopefully someone else will come along and have a better and cheaper solution, as I'm sure there is one or two still out there, with all the people here who burn DVDs and CDs.
