[linux-dvb] Twinhan DTV MiniCab DVB-C has many artifacts

[Jonek]

Hi (especialy Manu)!

I have a Twinhan DTV MiniCab DVB-C card (VP2021). This card has no CI
module! As I know from the archives people had problems with similar
kinds of cards. My problem is that if I tune a channel i get lots of
artifacts in the picture (but you can still recognize things) and nearly
unrecogizable audio. Please tell me how to fix this or what further info
you need.

I'm currently using kernel 2.6.15.3 and it's dvb modules:
dvb_bt8xx              11140  0

videodev                7296  1 bttv
v4l2_common             4864  1 bttv

If I use modprobe dst verbose=5 this is the dmesg result:
