HDHomerun - Signal not locked

Hi all,

I have setup an argus installation on a windows based system with an attached hdhomerun device following http://www.argus-tv.com/wiki/index.php?title=HDHomeRun.
Each time I start a recording, I am getting several "Signal not locked" messages from the card before the recording finally starts or not. I have also increased the "waiting for service PMT" to 20 seconds, but it seems that argustv is not waiting for a proper lock. Someone has a guess?

This is now repeating until the signal can be locked or it loops until the schedule ends without any recording.

I have done some more tests and it is definitely some timing issue. I have changed from "Reset when card is idle" to "pause when card is idle".
With pause I get the following behavior:

2016-08-23 13:43:47.3997 [Info ][Graph]: Signal locked, quality: 100%, strength: 94


After the first try, it fails again, but the channel stays open on the hdhomerun device (no reset anymore) and can be used on the second try in time.
Personally I could live with that as a workaround, but the whole tuner is blocked looking on the hdhomerun console:

Tuner 0 Status
Virtual Channel none
Frequency 442.000 MHz
Program Number none
Modulation Lock a8qam64-6900
Signal Strength 94%
Signal Quality 100%
Symbol Quality 100%
Streaming Rate 34.121 Mbps
Resource Lock xxx.xxx.xxx.xxx

Is there a way to tell argustv to wait more seconds to get the signal lock? I already increased "Wait for signal" to 20 seconds which sounds like the right parameter but it does still abort after ~2 seconds.

Did you change also wait for signal, for pmt, for signal decrypt?

Yes, sorry forgot to mention that. My current setup is:

PauseGraphWhenIdle = True
ResetGraphWhenIdle = False
TimeoutNoSignalSeconds = 10
TimeoutServiceDiscoverySeconds = 20
TimeoutDescrambleSeconds = 10
TimeoutScanTransponderSeconds = 60

Nevertheless I also tried to raise all values to 60, but it doesnt have any impact.

Ever tried to set the power values higher?
There is no risk in setting all of them to 120 and give it a try right?

Sorry type due to iPad trying to predict my wording.
I meant changing the card settings for timeouts to higher values.
In the recorder console you can change these

I already tried to increase them to maximum. No effect.

Yes, as already stated in the first 2 posts: It seems to be that the value TimeoutNoSignalSeconds is not fetched and it still timeouts after ~2 seconds. (default value is 1,5 seconds)
