mysterious folder

[Honey Bee]

Hi.
I have a folder called "Untitled DVD" on the righthand side of my finder window, under "PLACES" . I have no idea of what it is or how it got there. I cannot select it or highlight it to see whats in it. And I cannot move it or delete it. Nothing happens when I try to ctrl and click either. Should I start worrying? Anyone know what it is and how do I delete it?
Cheers Greg.

Got it sorted already. Did a search for untitled DVD here in this forum and my answer was to cmd+click+drag. Simple.
Anyone know why it appeared?
Happy new year. G.
