Yes there is sir.
To post vids, most people (now) load them onto youtube. I've never done this so i can't help much with that process.
For posting audio, or video for that matter, you can use yousendit.com.
For posting pics, and vids, you can use photobucke.com.
These are generally what the cats are using to post clips. All of these sites provide their services for free (YAY!). That aughta get you pretty well squared away.
Holla back doc!
