Comment 23 for bug 190291

So g_thread_supported() is the issue it seems and both Me TV and VFS plugin are doing the right thing. Me TV will not run without thread support, there's a thread that reads off the DVB device to write to the xine renderer, if that doesn't start you will not see video. I would guess that Glib thread support _is_ installed because your "#ifndef G_THREADS_ENABLED" will remove those lines so it will be same case that you had when you commented out the lines previously. Therefore G_THREADS_ENABLED is _defined_ which it should be.

If you like I can write you a small program to test this.
