The Hauppauge infrared receiver requires a remote control which speaks 
RC5 protocol. Basically the RC5 spec. allows to control 32 devices with 
64 key codes each. vdr uses approx. 50 key codes.

You need a remote control which
- speaks RC5
- can control 6 different RC5 devices

Enable ir debugging in the driver (pass av7110_ir_debug=1 to dvb-ttpci) 
and watch the 'addr' value when you press a key on the remote.
Your remote control must support 6 different device addresses or it will 
not work.

If you really have such a remote control I'll prepare a driver patch 
which will send the different device addresses through the input device 
to the remote control plugin. Then you can control 6 vdrs at the same 
time.

BTW, are you sure that your box will not crash if 6 DVB-S cards record 
or replay at the same time? Some people reported problems when DVB 
cards are sharing interrupts.
