I'm on Linux and using the rtmpdump tools as well as other old methods of trying to snoop the URLs for these videos. I'm not getting it for some reason. The Windows software located here http://www.allavsoft.com/how-to/down...bs-videos.html works in a virtual machine but I'd rather stay away from that. I need to update my skills. Can anyone give me a clue? I'd prefer to understand the latest method you use to grab the URL and I'll take it from there. Thanks.
