manifest.f4m - access denied - tricky one

[gabrusch]

I am trying to capture a streaming video with AdobeHDS.php and get it working to the step that it says "Access Denied! Unable to download the manifest."

The manifest url is:

http://zdf_hdflash_dach-vh.akamaihd.net/z/meta-files/tivi/smil/f4m/300/15/04/150417_longholiday_papa_lgf.smil/manifest.f4m

The webpage is

http://www.tivi.de/mediathek/detail.html?data=%2FtiviVideos%2Fbeitrag%2FDie%2Blangen%2Bgro%25C3%259Fen%2BFerien%2F2383962%2F2388676%3Fview%3DflashXml

Unfortunately the HDS Link Detector does not help grabbing the proper url. What is also very strange is that even in the browser console to open the manifest.f4m gives me an 403 FORBIDDEN when leading the page:

Any help is highly appreciated. Thanks!
