 New CAM modules for reception of encrypted DVB-S channels support a
 multitude of encryption systems. The resulting error appears to be :
 "CAM: ZCAS, 01, 02CA, 3000
 ERROR: too many CA system IDs!
 ERROR: too many CA system IDs!
 ERROR: too many CA system IDs!
 ERROR: too many CA system IDs!
 ERROR: too many CA system IDs!"

 Also, those newer CAM modules may be a bit slower to respond, maybe caused
 by the above.

 The result is that the CAM responds with:
 "CA: Sending CA_PMT with CPLM_ONLY to CI slot #0
 2008-01-16 15:31:04.392 DVB#0 CA Error: GetCaSystemIds returned NULL!
 (Slot #1)
 2008-01-16 15:31:05.673 DVB#0 CA: CAM: Menu Title: ZCAS
 2008-01-16 15:31:05.673 DVB#0 CA: CAM: Menu SubTitle:
 2008-01-16 15:31:05.673 DVB#0 CA: CAM: Menu BottomText: Press 'OK' to
 continue
 2008-01-16 15:31:05.673 DVB#0 CA: CAM: Menu Entry: No right to watch this
 program
 2008-01-16 15:31:05.674 DVB#0 CA: CAM: Selecting first entry"

 and the channel will not decrypt.

 I modified dvbci.cpp. This resolves the problems.
 Patchfile is attached. It's basic but it works for me. Don't think it will
 have negative effects for other CAMs but can't test this.
