I had to enable PCI bus mastering in BIOS on my computer before I could get 
any video out of the card. Also, you have to set some parameters on the board 
using the test_ioctl (distributed with ivtv) application. The lines below 
works for me. The setup is for PAL, so if you are in a country with another 
video standard you'll have to modify the lines below.

# Use PAL
test_ioctl -u 0xff

# Video input (this is the tuner on my card)
test_ioctl -p 4

# Set PAL resolution. I think MythTV does this so you don't have to.
test_ioctl -f width=720,height=576

# I had to lower my bitrate to get smooth playback
test_ioctl -c bitrate=2500000,bitrate_peak=4000000

# Audio setup
test_ioctl -v input=3,output=1

After setting all this up you should be able to do:
cat /dev/video0 > /tmp/first.mpg
^C

Hope this helps.

Best regards,
Tobias
