You're the expert when it comes to capturing streams so you're the first person I thought of...
On 4th of June there's Coldplay's Rock Am Ring appearance and apparently it'll be streamed live on this website: http://www.swr3.de/specials/rockamring2011/info/tv.php
It says "Simultaneously to live TV transmission it'll be streamed online on www.swr3.de/rockamring!"
Would you be able to record that?
I'll be working that night, no chance for me to try.
Those videos on the Kabel 1 site are annoying... they slowed down my PC immensely too.
So they are .swf files as well
I don't know what to do to capture it - it's not cached.
What I could do is record the sound...
Oh and you said you found it but it's not playing, right?
It was the same for me - the videos only showed up when I entered "Number one" in the search field above. So maybe try again with a proxy??
Send me a PM or post a visitor message when you see this so we can discuss what to do!
