Problems Ripping Certain Flash Video Content

I've got a question regarding some sites that use Flash video (.flv) and having difficulty ripping it. I've had no problems ripping Youtube videos, but when I go to The Tonight Show's Official Website and want to rip their flash video (from their concert series) I can't seem to rip those videos. I know it's a flash format, but yet I can't rip it. Can this not being able to rip be because the media is some how protect and can't be ripped? I use Replay by Applian Technolgies to rip Flash Video. Has anyone tried ripping any music performances from the site?

Flash is becoming popular not only due to its abilities, but that factor of user issues in replicating. The same protection is sometimes applied to simple images. Try saving the page ... luck may depend upon browser .... & then sepatate, but chances are not great afaik. Flash is less likely to be in an allowable permissable copy state. They obviously protect it for a reason ... copyright protection.

BTW Macromedia Director had a copyright option, so I presume flash does now also. Particularly if the non advancive, anti-competitive company called Adobe makes any calls upon this. They do now own flash.
