I'm not trying to criticize in a negative way but I kind of felt it important to mention that as far as espionage goes disabling the registry of the CD-ROM or whatever such solution to the 1 time view scenario is just unacceptable, as the media is still readable if placed in another machine, which the second time round could, knowing it'll fry the CD-ROM, redirect the output of the video to copy it.

So the Flash drive erase idea seems the best. Unless you could somehow access the CD-ROM to write over the data and make it unreadable. I would imagine you could gain access through whatever OS's device manager, but I really don't know much about direct hardware programming.

Just saying if we're being authentic spy types, data must be unreadable after use across multiple systems. 'This message will self destruct in..' style.
