Query: Software problem to be aware of

The machine works wonderfully, looks good; but people should be aware of a small, potent problem with the software. If you have (say) an internal CD-RW drive, and you're running Nero for it, this Sony DVD burner comes with its own version of Nero that wipes out your other version. And, this version of Nero will REFUSE to recognize a non-Sony burner of any sort. So, that's the end of your internal CD-RW drive! I bought this Sony for an office, intending to move it from machine to machine as needed, but this awful feature means I can't use it that way, because I would end up incapacitating everyone's CD burners. So, I have to keep it dedicated to a single machine. Might as well have bought an internal! What a design flaw, in an otherwise wonderful device! Whether or not this issue is of immediate concern to you, you really ought to be aware of it before you buy the machine.
