[QUOTE=DrageMester;2262175]Don’t perform disk intensive tasks while burning, such as e.g. running a virus scan. Depending on your system, your harddrive and how intensive the task is, your harddrive may not be up to the ask of performing the burn without slowdowns (burn stops/starts).
Running tasks that are CPU intensive but not disk intensive is usually not a problem.[/QUOTE]
Up til fairly recently I never did anything whilst burning, except maybe browse the net or check email.
Nowadays, with a couple of Core2Duo’s, I’ll generally listen to music or whatever (from HDD or memory stick) whilst burning. Even listening to music from a USB memory stick whilst burning to a USB ODD doesn’t seem to have any problems (YMMV on that one though).
