Another thing to keep in mind, most all sites that offer free video hosting also have in their terms that they can repurpose and use the content for other things, you still own the copyright but they can use the content as well. Its kind of the trade-off for free hosting. I am not sure of Blip's terms, but look into it.
So say your show takes off and you leave the service, they can keep running it and promoting it and grabbing traffic.
Sites that you pay to host don't usually have this stipulation, you are just renting space.
