I tried to burn Linux RedHat v9.0 CD#1 from a downloaded .ISO file using Nero 6.0.0.11. After I selected the image file, a popup indicated it was a foreign image ( ?? ) and asked to be corrected or ignored . I selected "ignore" and clicked "Burn" . Nero then warned that the burner was being used by another application ! There was no application using the drive at all , just the blank CD to be burnt . Please advise what was going on and how to proceed . Thanks... ( My system WinXP Pro SP1, Celeron 900 )
