Sopcast on Mac OSX - Solution confirmed
You need a few different bits of software but I now have sopcast working perfectly on my macbook.
You will first need to download "Crossover"
Once installed, open the program and install internet explorer 6 (the programme automates this process for you)
Then go to the Microsoft website and download the .exe file for Media player 7.
Open crossover again and select "install unsupported application" - browser to the media player 7 .exe and install
Return to microsoft and download media player 9 and repeat the steps above.
Finally download sopcast .exe file from the sopcast site and install as above.
Sopcast can now be run from the applications folder!
