I think DTube is very promising, but for some reason many DTube videos (including this one) don't always play right through for me despite me having a decent Internet connection. I'm in the UK, so probably currently further from the IPFS nodes.
Also, because DTube doesn't have adaptive streaming, it works best for people with slower connections if the uploaded videos are lower quality (bitrate) than usual, although maybe not for audio content ;)
Anyway, keep up the great work!
Yeah, Dtube is a monster project! I think it's on the right track... it's just going to need a big team and a lot of funding IMO
