Hi there,

I try to tune on a PID on HotBird and I can't get the status of the 
frontend to FE_HAS_LOCK.

If I plug an Astra cable on my PC, I can tune (on a another PID/freq/...) 
without problem.  And if I plug a set top box on that Hotbird cable, it 
works... So my guess is that it's not an installation issue (?).

After setting the SEC parameters, I set the tuning parameters. Then, I wait 
for the Frontend to send me a COMPLETION_EV. And I only get UNEXPECTED_EV 
and then I get FAILURE_EV...(failure code is 20 (decimal)).
After 20 tries, I get bored and I try to get the frontend status : the 
status remains HAS_POWER...

Has someone experienced that before ? Is there something I missed somewhere ?

Thanks in advance,
Sicerely,
Karim

PS : For the Audacious, here is test.c (in DVB/apps/test), I (quickly) 
modified to suit my needs and further down, you'll find the output.
