This is the first I've heard of DTube @titusfrost. Your video wouldn't play so I guess there are still a few bugs which need to be ironed out.
Probably because the file is freaking HUGE (~800MB) for a 10min video. It seems like DTube doesn't compress the video like YouTube does.
@titusfrost please consider compressing your videos unless @heimindanger changes the website to do it automatically.
