[linux-dvb] My Twinhan DVB-T CI won't tune

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I finally got my hands on a DVB card, and have started what is becoming
a very interesting proccess of getting it to work. Had to jump through a
couple of hoops to get the dst module to recognize it as a DVB-T and not
a DVB-S (the default KnoppMyth R5A16 install wouldn't budge on this
issue). Since then I've tried kernels 2.6.10 , 2.6.11.11 and 2.6.12-rc5
with the CVS version of dvb-kernel, but with similar results. The card
get's recognized as a DVB-T and the CI module is recognized, but when I
try to get dvbscan to do it's thing, I get "tuning failed" and a bunch
of error messages in dmesg. 

I've seen people have similar problems in the mailing list archives, but
I was wondering if there is any progress in finding a solution.

Regards,

Einar

dmesg output (using kernel 2.6.10 I get an error when I try to modprobe
dvb-bt8xx. Had to remove snd_bt8xx and bt878 before modprobe'ing it
again):
