mmm that seems interesting; where can i find manu's ca_zap ? what about 
your modifications ?  i have CAMs, a TPS card (HotBird) and CanalSat 
(Astra) card so I could see which combinations work ... and try to make 
other works ... I also noticed the dvb-bt8xx module init takes some time 
(3 or 4 seconds), so maybe there's something to do with it...
