I had been facing issues while uploading videos, and have not tried any more. I posted a question on your post as well as posted a question on the forum, but noone answered.
I think, its a great tool, but to make it popular, it must have great support till it matures.
If you can see my posts , comments and can respond, that would be great. You can respond here as well.
