There is such a thing as OVER protecting your content. If the masses don't know about it, they aren't looking for it, they aren't downloading it, they aren't buying it, and you probably aren't making any money off it. It was not too long ago when people were spamming their content all over P2P networks and newsgroups just to get some exposure that wasn't from a TGP/MGP. Now the new trend is tube sites, it's still the same concept.
I would love to see that sample stickyfingerz. You can't say "my videos can't be downloaded" and not even offer a public challenge. ;) If someone proves that your videos can be downloaded it gives you something to improve on. If no one can do it, that gives you more business. What do you have to lose?
