[vdr] Memory access error while attach player?

so I need to place the call at MainMenuAction or something similar?
Thats not what I want. I start a Thread in Start() which is listen to a 
xmlrpc connection.
If i get an "start Replay X" event from a xmlrpc Server, then I want to 
start a replay.
In this case I have to put my sockets to a thread but from a thread I 
can't start a replay :-(
Is the only way to use the svdrp? I can implement an own command which 
take my params, but this is a winded way, isn't it?
