Hi,

I finally got the drivers installed for this card thanks to you guys. I 
managed to make a channels.conf file using scandvb and it found all the 
channels.

But when I use tzap, I get results like this:

using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'
tuning to 714000000 Hz
video pid 0x006f, audio pid 0x0079
status 03 | signal 7c35 | snr 0000 | ber 001fffff | unc 00000000 |
status 1f | signal 7c38 | snr 0000 | ber 00000000 | unc 000008dd | 
FE_HAS_LOCK
status 1f | signal 7c32 | snr 0000 | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK

status 1f | signal 7c3d | snr 0000 | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK
status 1f | signal 7c22 | snr 0000 | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK
status 1f | signal 7c1e | snr 0000 | ber 000000c0 | unc 00000000 | 
FE_HAS_LOCK

I have used the card with Windows and had very good reception on this mux as 
well as other muxes with far worse signal (I have several roof antennas, and 
some channels/muxes are on amplified frequencies - like the one above - 
while others are not amplified. In Windows (dvbviewer) I can watch them all).

If I run tzap for one of the "bad" channels, ber goes up but the snr is 
still 0000.

The output above is for adapter1, but it's exactly the same for adapter0. I 
also tried running dvbstream, but it just creates an empty file (this could 
be because of a bad installation though? - I just copied the dvbstream 
executable to /usr/bin).

Any ideas?

Regards,
Thomas
