Hi,
I'm not sure that this is the right thread for me to put my patch for
libdvbsi, but it seems to me that the outcome of this thread will make
some changes to the libdvbsi, so it might not be such a bad place to put
my patch ;).
The patch stops the loop in parse_cab_channel_list function when the
channel is found.
It looks like this when I use it.

I'm to much of a newbie regarding DVB an CAM to make any conclusion what
this ca_zap log means. Is this the expected result? When I read
Documentation/dvb/ci.txt it says "(d) Hopeflly Enjoy your favourite
subscribed channel as you do with a FTA card." when ca_zap works, but I
do not understand how?
Regards,
