Hi David,
I know this is probably a DEAD topic now, but I just
got one of these Leadtek DTV1000-T cards to use with
Myth and I am getting the same results as you appear
to have, back in October 2005, from this thread.
When I run tzap, I get almost exactly (slightly
different signal - 002f from memory) the same results
that you reported (note I copied your results here
because I don't have access to my linux box at the
moment):
>> tzap -c
/usr/share/doc/dvb-utils/examples/channels.conf-dvbt-australia
>> "Ten HD"
>> using '/dev/dvb/adapter0/frontend0' and
'/dev/dvb/adapter0/demux0'

>> status 1f | signal 0030 | snr ffff | ber 00000000 |
unc 00000000 | FE_HAS_LOCK
>> status 1f | signal 0030 | snr ffff | ber 00000000 |
unc 00000000 | FE_HAS_LOCK
>> status 1f | signal 0030 | snr ffff | ber 00000000 |
unc 00000000 | FE_HAS_LOCK
I would guess that this means the card is working
properly, it's just that Myth cannot use it properly.
Did modifying the cx22702.c file get it working with
Myth?
FYI: I am currently running 2.6.15.4 Kernel and all
the drivers appear to have loaded properly. I also
have a TwinHan card and a Kworld VStream card working
with MythTV with absolutley no problems, so I'm pretty
sure there isn't a reception issue...
Any help is appreciated...
