I've tried it on eSteem and mobile-browser, but don't think I've tried it on Partiko yet. I've tried it on four different browsers on my laptop from two different hi-speed, broadband Internet connections, and know quite a few others who've had similar experiences, so something  is lacking with Dtube's streaming service. Vevo, Vimeo, and YouTube all stream seamlessly; it is a shame Dtube can't do whatever the other services are doing. Anyway, I will give Partiko a try next — thank you for that suggestion!
