chuckman45, I guess what you did is correct. So I suspect like Dani82 has said, check to see if your CD-Writer support overburn or not. To do that: 1. In action bar, select Recorder -> Choose Recorder 2. A Popup window pop up, and at the lower left corner will tell your chosen CD-burner will support overburn or not. If it does support Overburn, then also make sure you turn-off the multisession. It is the same window with the "Burn-at-Once", but in the 'Multisession' tab. Just select 'No multisession'. This is essential if you want to overburn a data cd. Cheers,
