[linux-dvb] Problem with AverMedia DVB-T card

[Joni Loponen <joni.loponen@auriamail.net>]

Hi,
I've tried to use AverMedia DVB-T card in Linux, but I didn't get
working. 
Here is what I've done:

1. Added necessary files from DVB-kernel CVS to Linux kernel 2.6-test4
2. Added kernelconfig for SP887X/Microtune 7202DTF
3. Applied the pathes in
dvb-kernel/linux/drivers/media/dvb/bt8xx/patches directory (seems like
Nebula patch is already added to bttv in this kernel) and made
Nebula-like addtions for AverMedia DVB-T
4. Removed #include "dvb_compat.h" from
dvb-kernel/linux/drivers/media/dvb/frontends/sp887x.c (Caused some
compile errors)


After compiling kernel I added a new initial transponder and tried to
scan for channels:
# ./scan
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
>>> tune to:
714000000:INVERSION_OFF:BANDWIDTH_8_MHZ:FEC_2_3:FEC_NONE:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE
WARNING: filter timeout pid 0x0011
WARNING: filter timeout pid 0x0000
WARNING: filter timeout pid 0x0010
dumping lists (0 services)
Done.


Then I tried to add a station to ~/.tzap/channels manually and use tzap
to tune it:
# tzap 1
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 714000000 Hz
status 1f | signal c0c0 | snr 4044 | ber ffffffff | unc ffffffff |

Here is my parsed kernel dmesg:

I've probably done something wrong with i2c adapter things, right?
Any help?
