Once it makes it to the internet there's no guarentee that it won't get shipped around. If you don't post it on the internet then your only real assurance against it becoming a widespread showing is by having only one copy and never letting it out of your sight. Do not share this sort of thing through the internet with your friends; since, friendships have been known to turn sour and to end at which point they could start selling your video for profit.how can I prevent it from being stolen online??
You can watermark the video and convert it to flv. There is software out there that can capture this though. I also would'nt use any of the tube sites. Buy your own webspace or have me host it haha
Hope this helps,
