[linux-dvb] ca_zap

Hi all,

 I hope i've not posted this twice...

 I have a Twinhan Ter-CI card plus a top up tv cam and an activated card. I have read the mailing lists and this has enabled me to get as far as being able to recieve and view all FTA channels (after upgrading to kernel 2.6.13 + dvb patches + additionally modifying DTT-CI to use NEWTUNER + HAS_CA).

 Im currently investigating ca_zap. Initially without much success until i read the post about it using the last channel information in the channels.conf and not the requested one. Now I have got it to the point where it seg faults, so i have done a  brief investigation with gdb and can provide the following info :

 The segfault is due to allocate_descriptor_storage returning a null pointer. and this pointer then being used a little later. I`m not at home at present so can't give any meaningfull dumps, but from what i remember... a descriptor_tag of 240 is being passed in with a length of 19. Now the switch statement obviously does not have a case for 240. So I`m unsure if this is even a legal tag, the fault could be prior to this point. I`m willing to investigate further and I believe Manu is the one working on this stuff, so I hope I can be of assistance.

 Out of interest is there a list of tags anywhere (I`m new to DVB stuff so I'm probably searching in the wrong places for the info i want at the moment). 

 Lee
