Hello

You can also add a video to your item on eBay by creating a blog on mybahia.
http://www.mybahia.com
On this website, you can add videos to your item, add descrition add as many picture as you want.
And it’s totally free.
Yet this website is really really new So there are still few bugs ( especially with internet explorer) and it not yet crowded but I’m sure that it’ll be fixed very soon.

Enjoy
