I had the similar problem, this is my solution:
1) i saw an error (ImportError: No module named vlc_1_0_x)
2) goes to /usr/share/sopcast-player/lib/
3) do "ls -la | grep vlc"
4) output: vlc_1_1_x.py vlc_1_1_x.pyc
5) there is no vlc_1_0_x!
6) making a hardlink "ln -s vlc_1_1_x.py vlc_1_0_x.py"
7) trying to launch sopcast - it's fine now.
