Just like you are responsible to read all the posted reference material, you are also expected to view/understand the RFID videos posted on the reference page
I advise you to download and save these videos for later offline viewing. There are many tools for downloading youtube vidoes - download the top one from download.com
my favorite is real-player. It has an option there is allows you to download videos playing in your IE or FireFox browsers. you can download the free version from real player website. Once installed, open preferences and go the last option (Download & Recording). Then select checkbox to enable downloads, and restart your browsers.
