1.36 Hauppauge WinTV-NOVA-S2 DiSEqC (2 Viewers)

[AberDino]

Due to ongoing issues with my TBS5520SE USB tuner, I've invested in a Hauppauge WinTV-NOVA-S2 tuner. I have a multi-LNB setup (19.2°E / 23.5°E / 28.2°E) with DiSEqC 1.0 switches (twin LNBs for each).

I also had a TBS5980 before, and DiSEqC worked without any issues on both TBS tuners, quickly switching between the various LNBs. Unfortunately, not so with the Hauppauge WinTV-NOVA-S2 tuner, as it only seems to be able to use the LNB connected to port 1 (Level1AA). Tuning to channels on port 2 or 3 is unsuccessful. See log attached, where I tune to the "BVN" channel on 19.2°E (port 2 - Level1AB), first successfully with the TBS5520SE tuner and then unsuccessfully with the WinTV-NOVA-S2 tuner. In order to test the WinTV-NOVA-S2 tuner DiSEqC functionality, I installed the Hauppauge WinTV 10 software and it works fine there, so it appears to be a MediaPortal issue.

Is anybody able to assist with this? To be honest, I had expected this tuner to work without any issues, but I have now found some older posts regarding DiSEqC issues with Hauppauge devices. Is it possible to increase the delay after switching to see if that would help?

Does this page in the MP Wiki help?

I found that page by using the search facility to search the Wiki for diseqc. There are other hits in the Wiki, which may also be worth reading.

Thanks @CyberSimian, yes, I did see that same article, which is associated with this post. It dates back to 2016 and relates to a different Hauppauge product, and as it involves installing very old driver files (2010) for a different make of product (TechnoTrend), I've been hesitant to try it, i.e. I don't want to mess up my Windows 11 install. However, by the sounds of it, I might just have to give it a go .

I also found this post, which is in relation to the same product as I have, but without a solution.

My (possibly faulty) recollection is that the DiSEqC support in TVE3 in MP1 has some problems, and not all tuners are supported. I think that the newer TVE3.5 was going to solve these problems, but sadly it was never completed, and the developer who was working on it retired some years ago.

MP2 incorporates three TV servers: TVE3, TVE3.5, and TvMosaic. So MP2 using TVE3.5 may actually work correctly with your tuner. Unfortunately, the version of TVE3.5 included in MP2 is incomplete, and so that TV server has other problems (but if you have some time to spare, you might like to experiment with it).

I regret to say that I think that the situation with DiSEqC in MP1 will not change, due to the lack of a developer with the necessary knowledge.

I've read some articles related to BDA diseqc issues. It seems that the diseqc command has to be send after putting the tune request to the driver. You can try this experimental modiffied dll. The modified dll version should execute diseqc command again after the tunning process is done.

Hi @Pablik, thank you for compiling the experimental DLL. I've tried it, but unfortunately it makes no difference. Looking at the TVService.log (as attached), the entries following the "CardTuner.CartTune" line are identical, so is that what you would expect, considering "the modified dll version should execute diseqc command again after the tunning process is done"?

 

[Pablik]

Please, download the updated dll again and try it.

I downloaded the "TechnoTrend TT-budget BDA-driver 5.0.3.6", had a look at the inf file, and I can confirm that it does not contain a device string for my device, so I did not install it. I did try renaming the KNCBDACTRL.dll file as suggested, but that didn't make any difference.

Sorry @Pablik, still the same, including log entries following the "CardTuner.CartTune" line.

Just to check, I stopped the TVService, renamed the "TVLibrary.dll" file in the "C:\Program Files\Team MediaPortal\MediaPortal TV Server" folder to "TVLibrary.dll.org", copied in your modified "TVLibrary.dll" file, and started the TVService. I don't need to register the DLL I presume?

Sorry my bad, please try again.
