How to get a picture from analog tv card bt878

Hello.

I was following this guide: http://wiki.archlinux.org/index.php/MythTV_HOWTO to set up tvstation But I haven't found anything related to driveres and support of the tv cards. There is mentioned that bt878 is supported but how can I know for sure?
This is my card:

02:07.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
02:07.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

On this wiki I haven't found informations how to load a module if any in order to get support  for this card. So I have installed tvtime from AUR and tvtime-scanner --input=0 won't found any information about channels.... More detailed output:

tvtime-scanner --input=0
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/vida/.tvtime/tvtime.xml
Scanning using TV standard NTSC.
/home/vida/.tvtime/stationlist.xml: No existing NTSC station list "Custom".
Scanning from  44,00 MHz to 958,00 MHz.
Checking 693,75 MHz:  - No signal

How can I test if this card gives any picture without modules loaded? At least not additional...
I have Linux ardoma 2.6.32-ARCH #1 SMP PREEMPT Tue Feb 9 15:12:10 CET 2010 x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
No custom kernel.

Accorting to this page: http://www.faqs.org/docs/Linux-mini/BTTV.html#ss4.5 bttv is the module I need and it's already loaded in the kernel:

$ lsmod | grep bttv
bttv                  114010  1 
v4l2_common            13160  5 tuner,tvaudio,tda7432,msp3400,bttv
videodev               35771  7 tuner,tvaudio,tda7432,msp3400,bttv,v4l2_common
ir_common              24608  1 bttv
i2c_algo_bit            4935  1 bttv
videobuf_dma_sg         9099  1 bttv
videobuf_core          13657  2 bttv,videobuf_dma_sg
btcx_risc               3155  1 bttv
tveeprom               13081  1 bttv
i2c_core               18137  12 nvidia,tuner_simple,tuner,tvaudio,tda7432,msp3400,bttv,v4l2_common,videodev,i2c_algo_bit,tveeprom,i2c_nforce2

Now I've scanned for signal with s-video and television mode with a command tvtime-scanner --input=0 and in both cases I get no signal from 44,00-958,00 MHz.

How can I test if there is a picture?

keep bumping, nothing good will come out of it.

if noone answered, noone has the answer.

try kdetv and see if it works. thats all i can think of. ive had issues with tvtime in the past (none like the one you describe)
