I use Tube Mogul which is free and is easy to use to submit videos to the popular sites.

I've had good success with TubeMobul its an online service for video distribution.

Another vote for Tube Mogul

TubeMogul does video submissions.

Yes but tube mogul is not like before, because people make a lot of spam. For me today TM is totally useless.

Have to say that i do like tube mogul
