(I searched for this and haven't been able to find it so please just direct me to a link if i am repeating an old question.)

Is it possible to put my edited movie back onto my P2 card? Right now it is my only real HD playback device, and it would be great to see footage edited rather than just clips.

You can "print to video" back to the camera; Apple published a document outlining the steps to do so.

Found it here: Workflow for Final Cut Pro and the Panasonic AG-HVX200 HD Camera (http://www.rainbow.gr/markets/pdfs/Video/FCP_Workflow_HVX200.pdf).

Thanks Sam & Barry, that's exactly what I was looking for.
