Subject: Problems with tuning (only after a while) and Nexus-S
Date: Tue, 19 May 2009 19:48:22 +0200 [thread overview]

Hi,
since some days I have problems with my Nexus-S v2.3 and tuning. dmesg says
this about the adapter:
DVB: registering new adapter (Technotrend/Hauppauge WinTV Nexus-S rev2.3)
adapter has MAC addr = 00:d0:5c:04:f4:2f
dvb-ttpci: info @ card 0: firm f0240009, rtsl b0250018, vid 0f12623
dvb-ttpci: firmware @ card 0 supports CI link layer interface
dvb-ttpci: Crystal audio DAC @ card 0 detected
saa7146_vv: saa7146 (0): registered device video0 [v4l2]
saa7146_vv: saa7146 (0): registered device vbi0 [v4l2]
DVB: registering adapter 0 frontend 0 (ST STV0299 DVB-S)...
input: DVB on-card IR receiver as /class/input/input12
dvb-ttpci: found av7110-0.
Kernel version is 2.6.29, though this happened in my old machine with 2.6.22
aswell. Firmware is dvb-ttpci-01.fw-2622
After some hours of tuning (delay 5 seconds to stress-test the machine), it
will not get further than FE_HAS_SIGNAL and FE_HAS_CARRIER. Only on the
ProSiebenSat.1-transponder i still get a lock, which i find quite odd.
Could it be the cable being badly shielded? Or may it be the LNB failing?
We had some issues with an analog receiver (on the same LNB) displaying
interferences.
I already tried disconnecting the analog receiver to make sure it doesn’t
interfere with the DVB card, but that wasn’t the problem.
Any other ideas what I could try?
Enabling the debug options of the driver led to the following output:
DVB: initialising adapter 0 frontend 0 (ST STV0299 DVB-S)...
