First of all, here's the output of "lspci -v" for my card:
--------------------------- 8< 8< 8< -------------------------------
0000:02:07.0 Multimedia controller: Twinhan Technology Co. Ltd: Unknown
device 4e35 (rev 01)
        Subsystem: Twinhan Technology Co. Ltd: Unknown device 0008
        Flags: bus master, medium devsel, latency 64, IRQ 7
        Memory at f6000000 (32-bit, prefetchable) [size=4K]
--------------------------- 8< 8< 8< -------------------------------

The card is TwinhanDTV Cab-CI (Mantis 2033), same as
http://www.twinhan.com/product_cable_2.asp.

The story:

- Compiling went nicely, but "make install" didn't copy cu1216.ko under
/lib/modules. I had to copy it by hand.

- Loading the modules worked fine. Output of dmesg after loading the modules:

--------------------------- 8< 8< 8< -------------------------------

- I get no picture at all. Looks like it doesn't even see the signal,
because if I plug and unplug the RF cable, I see no difference in czap output:

--------------------------- 8< 8< 8< -------------------------------

--------------------------- 8< 8< 8< -------------------------------

After running czap, I got the following out in dmesg:

--------------------------- 8< 8< 8< -------------------------------

[cu1216_set_parameters]:frequency = 418000000 , symbol = 6900000 , qam = 4 .

mantis stop feed and dma
--------------------------- 8< 8< 8< -------------------------------

Also running "dvbsnoop -s pidscan" produces no output. I have another DVB-C
card in the system at the same time (Terratec Cinergy 1200 DVB-C) and it
works fine with my setup.

DVB modules (and other relevant ones) that I had loaded (my system also has
DXR3 card, em8300 is the module for it):
