DVDVideoSoft would be your semi-auto uploading software. It has some advertisements within the setup, so make sure to untick those options. It's free, though - and quite stable. The bad thing is, you have to edit all of your descriptions yourself - which you can do by simply using some kind of mouse recorder.
For full auto, use Mass Video Blaster. I'd personally go with uploading 1 video and trying to get it ranked, but each to their own I suppose.
Good luck!
