i guys i totaly forgot to tell you about this. I was talking with a sony guy while i had my hands on playTV and i told him how disappointed I was about the fact that you cannot move stuff. Well he showed me something very interesting. You cannot move the videos from PlayTV to other devices indeed but you can move the videos to the XMB
Well you all probably know what happens if you press triangle on the XMB ;) I tried it me self with me USB stick and it really works.
