Well said!
I think it's important that we all support Dtube, so that it can get to its "final form". I think the concept is great, but also still rather young. So of course they need people to test the service in order to work on the functionality and other aspects of it.
I basically see it just as steemit: It is a beta. It is like testing out a game and reporting things that you think are missing or reporting bugs (for example the problem with the embedded player you mentioned). I think that our feedback is the most valuable for the developers.
And as of now I think they will take into account what we say. Because they care, or at least that is how I see it.
