I wonder what video format he's is using for the video clips? Or what version of Windows Media Format he is using. My Windows Media Player states that the formats are invalid and refuses to play them.

I recently bought a roomba and it works really well. My sisters 2 and 4 year old kids absolutely love it and have spent a lot of time "feeding" it different types of junk - crushed biscuits, dust, bird seed, etc

My floor has never been so clean.
