[linux-dvb] Nexus-s video feed lost (Card/Diseqc Issue?)
Hi,
I was working on some diseqc software experiment on mythtv, and got is
half-way working, meaning that channels with specific pol etc parameters
did tune while others did not... Anyhow, during this work I at some
point just lost the Hauppauge Nexus-S card. I have not been able to view
satellite channels with mplayer dvb://, and tuning with szap sets the
BER quite soon to 00000. I checked that on the cable to diseqc the card
is still giving 17.5 volts, and even tuning to V pol channels keeps it
there.
I have the DVB build from yesterday - and I cannot confirm did this
problem show up as a result of updating to the latest DVB or as a result
of something happening while accessing the DVB API.
In the nexus-no-feed is output of szap where BER turns to 0000 after
lock, and corresponding dmesg with frontend debug on.
In the diff you can see the diseqc stuff should be fairly std - I
assume.
Any ideas on this one?
