are you trying to upload or import? I didn't have any luck importing, but uploading works for me.

bigger file size takes quite awhile (I'm sure it will improve) once the video has uploaded and you've filled out the info then click the "upload" button it will take you to a blank page. wait a little bit then click "back" in the browser and let it sit, with in a bit you'll get an email confirmation that the video has been uploaded  (I watch vid's etc in other tabs while I'm waiting)

the site will be much smoother and functional once completed... the road map is pretty clear that it's going to get better

I've added a few more
