Hi mm,
An update after using your patch for a few days.
Definately a big step forward - everything seems to work (scanning, tuning DVB-S and DVB-S2, diseqc switching). The only problem is that after a while (about 24 hours) it stops working again until I reboot.
The attached logs show a typical sequence :
Don't know if these give you any more info but thought they were worth posting in case.
One other question - can I use your patched dll with 1.2.1 or should I stay with 1.2.0 for now?
Regards
C

Reboot in the evening, watch some TV - all OK
Next morning the first tuner in the KNC fails and MP falls back to the 2nd.
At some point in the evening the 2nd tuner on the KNC drops out and MP falls back to the TT card.
Reboot server and start again.

Hi again
The DLL can't be used with 1.2.1 - I'd need to recompile. Then again, I don't think you actually need it all that much if you're not using the tuners with CAMs. Simply ensure that the "preferred network provider" setting remains on "DVBS" rather than "generic" and 1.2.1 should work just like 1.2.0.
Regarding the problems: are either the tuners being used with "pause card" ("when card enters idle state..." - also a tuner setting -->here<--). It looks like they may be, but I'm not 100% sure. I would switch this to "stop card" if they are on "pause" and see how you go.

PS: I heard back from morpheus_xx last evening so I'll see how I go with providing a new DLL. I'll assume you'll upgrade to 1.2.1 so I'll target that version with any changes that I make.

I think you're right - I definately set the tuner I was testing with the other day to "Stop" & "DVB-S" but I probably forgot to set the 2nd one when we were done.
I see that 1.2.1 defaults to "Stop" so I think I'll wipe 1.2.0 and install 1.2.1. I'll try with the dll in that release and both KNC tuners set to DVB-S. Hopefully that should just work.
Then I'll be able to try out a patched dll when you have time.

Hello again,
I used 1.2.0 and your patched dll a little longer (with both KNC tuners set to "Stop" & "DVB-S" this time) and got quite good results. Everything worked and both tuners stayed available for much longer. Just by the 3rd day I got one of the tuners dropping out as before.
Now I've removed 1.2.0 and done a clean install of 1.2.1 and the results are not as good - I think you might be underestimating the effectiveness of the changes you made in the patched dll.
The logs attached show 1.2.1, an attempt to scan satellites on 1 KNC tuner (worked), an attempt to tune to SD channel on both tuners (1 worked, 1 failed), an attempt to tune to HD (DVB-S2) channel on both tuners (both failed) and finally another attempt to tune to SD channel on both tuners (again 1 worked, 1 failed).

Hi again
You may be right for the HD channels, but the issues with tuning SD channels on the second tuner... that is a different story. I have no idea what is going on there. The tuner either returns "no signal" or "no PMT found". I suspect restarting the TV Server and/or the computer may help. I strongly suspect that the drivers are having an influence here. I may have already asked this, but are you using the latest drivers? Anyhow, here is a DLL for 1.2.1 that will hopefully get your HD channels working again.

Thanks for the new dll - I'll try it out and let you know how I get on.
I was on the latest driver as of a couple of weeks ago but I'll check again in case there have been any recent updates.
As you may have noticed from the last logs I've replaced my tt card with a TBS6981 (thanks for pointing me in the direction of this card) and it has worked flawlessly since I first plugged it in.
The KNC card with your patched DLL is OK but it still occasionally fails which for watching live TV is no big deal but if it causes a scheduled recording to fail it could cause some friction here
My question is - do you think that it is possible to get the KNC support to be as solid as the TBS (maybe with the feedback you got from morpheus_xx)? If so I can stick with the KNC for a while. If not, and it is just a question of hoping that KNC release better drivers sometime soon then I'll seriously think about binning it favour of a second TBS card.

It is hard when I don't know what the problem is exactly. Are you able to provide logs showing the problems that you're experiencing?
I asked morpheus_xx a specific implementation question not about general stability issues which he may or may not know about. His focus is on MP 2 so I don't want to distract him.

The problem is still the same as before - sooner or later the KNC tuners can't tune to a channel and just return an error like "No signal" or "Unknown Error" as you saw in the previous logs. Once that happens the tuner is effectively dead until I reboot.
With the dll in the release package this happens within a few hours. With your Patched DLL it is much better and doesn't happen for a few days.
If you're coming to the conclusion now that problem is down to the driver not behaving properly then there's probably not much you can do and it's not worth spending more time on - I can see in the forums that you have plenty other things to deal with!
It would be nice to get another card working properly but if that is not possible then you have already given me another solution - the TBS card.

Hi again
What I meant about the problem and logs is more about finding out whatever is triggering "it". Whether it is a driver problem or an MP problem is not something that I have closed my mind about. I think it is still possible that your use of DiSEqC without the full/proper implementation may be causing problems. Please if you're able... post TV Server logs showing the first time when you realise that one of the tuners has "stopped working". It is possible that I can go back through the logs and find out what triggered it. In the meantime, I am still looking into how to implement the KNC DiSEqC interface - I hope I will have something to test by the end of this weekend.
