Hello mate, ok I think I know what is going wrong here.
Log into Dtube with your dtube account and then sign in with you steem account.
Put in your youtube link into dtube and it will pull up your video and your written text you placed in youtube.
Then click upload. Dtube will automatically post your video to both dtube and Steemit.
Does this make sense?
Thanks for the advice, but I'm just writing about the videos. I already posted these to Dtube.
