Problem recording RTMP flash music video stream from walmart site

Hey, I've tried many of the programmes mentioned on this site and still havent been able to rip the video from this site...

I don't know if there is a specific reason for me not bieng able to rip it such as copyright or something of if its just my laptop (or possibly my stupidity)

Anyway, any help which you guys can offer would be greatly appreciated, thanks

Also im a newbie so please be gentle with me, lol
