Resolving streaming media links

[TimoTimo]

I'm currently coding a script to get links from web sites, and there are often streaming video/media sites it comes across where it can't get the actual links of where the streaming video is really coming from. For example (and there are plenty of sites where i have this problem on), the site http://tv-links.co.uk/listings/2/141 or http://tv-links.co.uk/video/2/141/370/4956/8716 uses some method to mask the links of where the streaming video is really coming from, there is no place in the source of the pages that tells where the video is really coming from. That site tv-links hosts no media (along with all the other hundreds of sites i'm having problems with), so don't be fooled by their links. I have a program called httpwatch that works in conjunction with internet explorer and it can resolve the exact link of where the video really comes from but that of course has nothing to do with PHP, but atleast I know it can be done. I'm stumped as to where to start coding in PHP to get the links. Any help or useful info of any kind would be very much appreciated.
