90 Minute Cd's

[ukcalibrauk]

Does that mean that I can only `overburn` using disk at once with Nero

I have ticked overburn, to make a data compilation disk with Nero, but it still tells me my disk is too small and the bar at the bottom of the screen does not move to a bigger size. is it possible to overburn and make a data disk with nero.....If so can you please tell me how


Thanks

PS I bought some 90 minute CD's but Nero and Feurio reprt them as 80 minute, maybe I've been conned
