Thanks to 
For any Video hosting service to be popular we need atleast two things. Ability to embed easily and easy integration with CMSes. So I Spent some time writing a module for Drupal Dtube integration this weekend. The first release for the module is ready and is available on https://www.drupal.org/project/video_embed_dtube. You can install this module like any other module and enable it. Once you enable this module you will have Dtube as an additional provider in the video embed field.
Once you check the option of Dtube for this field you can go to create content page and add a link to any Dtube video in the field like below.
Once you add the field it becomes visible in the node view page as show in the image below.
There is one bug https://www.drupal.org/node/291636. If you know how to get the thumbnail from the video link do let me know in comments so that I can fix the bug in my free time.
