Dragging & dropping files from a Mac to the Playbook via USB issue

I am attempting to drag & drop movie & pics files from my iMac desktop to the playbook and receive the below message.


Items can�t be copied to �media� because you don�t have permission to read them.

make sure to copy them to one of the subfolders inside media (eg. pictures, videos, misc, etc.) there is no r/w permission to the root media folder.

if this fails, give the wi-fi media share a try instead.

Hello!

Typing this gingerly on my new PlayBook... Trying to get used to the interesting predictive text. Anyway, my question is similar to the original post. I want to drag files directly to my PlayBook from my Mac but when I connect it with the usb cable it doesn't show up in finder . Under storage and sharing I have file sharing turned on.

Any suggestions?

Thanks, Mellfee. (loving the playbook)
