Deleting video files in Boxee

Please be gentle with this new user!

I have managed after much trying to transfer a couple of videos over to Boxee on my ATV1 using Cyberduck. As I’m new to all this I don’t know if this is the best or easiest way, but that’s what I’ve done. I can find both videos in Boxee files and play them, trouble is I can’t see how I can delete them!

There doesn’t seem ‘delete’ option attached to the videos. Pressing the limited number of buttons on the ATV remote doesn’t provide me with any option to delete the files.

How on earth do I do it?
