Lars, unfortunately not true. Anyone can easily download your video to their laptop and do with it as they wish.
PapaBear, agreed BUT as you know what's legal and what people do are two different things.
I only bring this subject up because I think that few if any people give any thought at all to what happens to their video once it's posted and how easy it is to misappropriate. Had this discussion with a colleague of mine about his video on Vimeo and to prove my point pulled down his HD short, cut it and sent it back to him in HD and with little if any picture degradation. Got his attention real quick.
