Hey I used skynet to upload this file and I have linked it on my dtube account just to test how and if it works. After I reduced the size (and quality) of the video, the upload and processing has been quiet quick. I will research & test more about this and all the other methods to "upload" files onto dtube. We'll see :)
But for now I can say: DTube and the multiple ways to upload/link your videos is outstanding! I dont know any other platform granting this kind of diversity!
