Has anybody used these videos on Windows 2003 Server?

[Mavro]

I was searching for a cheap(Actually free) way to learn Windows 2003 Server, and I came across these videos. They are not free, but only 10 bucks. The free demo video seems pretty cool, but before I bug my parents to use their Credit Card I would like to know if they are worth it? My parents are leary about using their card on the net. Has anybody seen these and are they worth it? Thanks
