I have to agree with @ohmano on this one regarding D.tube. Still too beta (or even alpha) to be very user friendly. That said, I agree with you that it has HUGE potential, and I'm confident that the devs will work the kinks out. When they do....

In the meantime, @ohmano, Suppo is still posting his vids to YouTube in addition to here. You can just go watch them on his channel there instead.
