Hi,
I've got a Hauppauge Nova-T, and I'm having trouble getting any
tuning application to achieve anything sensible. I'm using the linuxtv
drivers (rather than the Metzler ones), v1.0.0-pre2, with a
2.4.21-pre5-ac2 kernel. My experiences so far:
hrm@vlad:src $ /sbin/lsmod
Module Size Used by Not tainted
dvb-ttpci 295312 0 (unused)
videodev 5856 0 [dvb-ttpci]
grundig_29504-401 3560 1
dvb-core 38980 3 [dvb-ttpci grundig_29504-401]
[snip...]
hrm@vlad:scan $ ./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_16:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE
>>> tuning status == 0x01!!!
>>> tuning status == 0x01!!!
>>> tuning status == 0x01!!!
>>> tuning failed!!!
[etc...]
I'm in Southampton, which should be the Hannington transmitter.
From [1], I tried dvbtune:
hrm@vlad:src $ dvbtune -c 0 -f 706167 -i
FD 6: fd_dvr DEMUX DEVICE: : No such file or directory
No luck here either. It works (approximately) in WinXP: I'm missing
some of the multiplexes (I can't get ITV, C4 or C5 yet -- need a
better aerial I suspect). However, I am getting a strong enough signal
that I can pick up at least the two multiplexes carrying BBC1 and Sky
News, so signal isn't a problem for testing purposes.
What, if anything, am I doing wrong?
(Also, is there a good explanation anywhere of the terms used in
tuning, such as QAM, PID and the like?)
Hugo.
PS. I'm using devfs, if that makes a difference.
