Hi Neil, I don’t have any Roxio, or norton utilities. I have an anti virus but even tried burning with turning off everything I could on the right hand corner task bar. Also, don’t have any of the other things you mentioned. I don’t have alot of stuff on this computer as I use it mainly for working and have a networked computer that I use for email and stuff like that. I went and bought Verbatim +r and it burned right away, no problem. I also stopped and talked to the computer people that built my system and they also thought it might be a software issue so will have them check it out as I am afraid to delete anything that I didn’t install myself. Thank you so much for your time as it steered me in the right direction. Thought I might be missing a setting in Encore or something. Donna
