I have had a hell of a time uploading videos to DTube. I blog about my experiences in further detail here.

But basically I was unable to upload anything to DTube. Today, however, I am pleased to announce that I have found a solution. These are the steps I use, I don't know how or why it works, I just know that this works for me.
- Use The web browser Chrome.
- upload your video to youtube
- copy your youtube video address
- open www.y2mate.com
- paste address into the y2mate form as directed
- download the new mp4 video file from y2mate to your computer
- upload that new file to DTube
I hope this works for you too.
Disclaimer: use the website www.y2mate.com at your own risk. I have no affiliation with the site. I have had no problems using the site. I have read nothing bad about the site. However you are downloading a file onto your computer from it.
Good luck!!!
Please let me know if this works or not for you.
