I'm glad for you and others that have been able to use DTube successfully. I wish it worked for me too, but it doesn't. I don't know why it doesn't, but it doesn't. The only way I can post a video to steemit, is to post it to youtube first and drop it in a steemit post. I'm sorry, but that's just a truthful summary of my experinces after trying to upload 6 videos on DTube which all failed, and which I then had to delete. If DTube gets to where it's reliable, I will certainly use it.
