now I have rewritten all my code. It seems to work.

this function finds a device which can provide a receiver without detach 
any receiver. (independent of the prio)

bool needdetach = false;
bool found = false;
for (int i=0; (i < (cDevice::NumDevices()-1) && !found);i++){
   device = cDevice::GetDevice(i);
   if(device->ProvidesChannel(channel,PRIOCHANGECHANNEL,&needdetach) && 
     //device can Provide Channel and no receiver has to detach			
     found = true;
     device = NULL;	

on the found device i can add myreceiver with Prio -2

additional I observe all myreceiver. If I want to add a new myreceiver 
to a device I will look at my local List, if I have already added a 
receiver to the transponder. If I found one I will add my receiver to 
the same device.

But now I need to recognize if vdr has detached my receiver.
So I have used void cMyReciver::Activate(bool On) to recognize if it 
will detach. The Problem is, that it will only be detached if vdr will
