[vdr] Problem with transfer mode, xine plugin and ActualDevice

Well, I don't know where the problem actually lies (I guess the xine plugin), but:

I'm using vdr with a dxr3 and the xine-newtork plugin (0.7.4, I know I should update it, but I couldn't spot anything related to this problem in HISTORY for 0.7.5 and 0.7.6). Normally the dxr3 is the primary device but when the xine plugin is in use it will switch itself as the primary. The problem is that right after the switch a new transfer thread starts *before* the previous one ends, so receiverDevice is left pointing to NULL, so that ActualDevice fails to report the correct device, until the next channel switch.
