DVD Write Problem

[ftg]

This is probably a stupid question, but when I drag an ISO file to the Clone/Burn screen in order to burn it, I get an error popup saying that I need an optical drive in order to burn ISOs. Of course, I have an optical drive (two, actually) and Common Settings -> Drives sees both of them. Reading for Clone/Burn works fine. What do I need to do to be able to burn ?

Hi there, can you provide the names and model numbers for these optical drives? Have you burned discs before with these drives? Perhaps you have optical drives that are disc readers only and not burners?
