I have a Vu+ Solo SE running the latest image, with a CI and a valid subscriber card.

 

All my channels on DVB-S work fine, but any channel on DVB-S2 just shows a black screen and no audio.

No error from the CI or anything.

 

Does anybody know why this would happen?

Try a FTA service first. What is the reception quality (SNR)?

FTA DVB-S2 is fine and signal is fine as well works on another receiver.

You probably needs to enable the high bit rate option on your CI module.

I thought it might be that as well I already tried that.

Not relevant, ci is a smit professional module which has been confirmed to work in the past and in other receivers.

Is it a CI+ module?

For DVB-S2 be sure that high bit rate must be set to ON.

 

Did you use both a softcam (OScam, CCcam,...) at the same time as your module? If so please stop your softcam and test only with the CI Module.

Also remove and replug the module to reinitialise it.

High bitrate is defiantly on, and never used a soft cam just a valid card and ci from subscriber.

No it's just a regular old CI module, it's like 7+ years old.

 

Tried some more stuff.

I flashed BH and still had the same issue.

Flashed OpenVIX and v4 just shows black same as the others, but v5 shows me a tuner configuration issue and the only those DVB-S2 channels are grayed out on the guide.

 

I'm really not sure what's going on, I know the feed is coming in since the bitrate viewer extension shows a bitrate and if I stream it into TSReader I see the feeds and PMT (It's still not decoding in TSReader either black screen)

 

I also tried a FTA DVB-S2 channel and that displays fine so it's not my tuner not supporting DVB-S2 or something.

 

Oh I'm blind scanning to find these channels so I double checked the DVB-S2 channels are being idenfied as 20 HDTV not a data channel as well, even tried switching them to TV id as well no dice.

I have a work around it's very strange....

 

Zap to HD channel, start stream to TSReader, scrambled channel.

Zap to SD channel, leave TSReader open on HD.

 

TSReader which was left open starts to show picture no longer scrambled for HD channel, Vu+ is black on the TV though, shows as being on the SD channel.

(SD and HD are on the same MUX)

 

This really seems like some kind of a software bug with the CI interface or something, I can't understand it or explain it. I'm at a loss.

Have you considered checking your CI module. If it ís 7 years old it may be dying. They tend to get quite warm during use (sometimes even downright hot). Perhaps you should try a new one? What kind of CI module and provider are we talking about? Have you tried the Common Interface Assignment function to 'force' the HD channels to be handled by the CI module?

CI is working fine trust me, works fine in another receiver.

 

Tried that as well no dice, the problem is it's a total black screen, there's no error there's nothing to point me in the direction of something to debug.

If the CI was erroring I'd get an on screen message about the channel being blocked or the smart card being invalid.

 

I removed some DVB-S2 channels from my package and the CI instantly errored about them being blocked services, then I added them back and the error went away and still the same black screen.

You are still very evasive. What channels? Which provider? Which Ci. Come on mate! Spill the beans

I've already said which CI it is and the provider and channels wont help, since I doubt anybody around these parts would have that provider.

 

I'm being evasive due to the way the provider responds to people who have used 3rd party receivers in the past, but I'm paying for the subscription more than $100 a month, I should be able to use whatever receiver I want since the ones they provide are complete trash.

 

If it becomes necessary to provide that information I will to a dev in PM and I'm more than willing to work on a fix myself and send a pull request, but before I go spinning my wheels doing that I want to see if it's something else I may have missed.

In that case you are better off with a forum/community that covers your region. In these posts I cannot find any info about your CI (other than you stating it's an old CI and definately no CI+). Those HD channels are probably send in a non-DVB standard for a reason. Since it is not in our region (we cannot receive them) it stops here..

I can just provide dumps but they're to specification. They aren't muli-stream ect I've checked, you're not talking to a layman here I've committed code to the project before and if I need to I will again to fix this.

The only thing that was a little odd is the DVB-S2 channels are beamed twice with multiple service ids.

 

As I said it's a SMiT professional CAM, the provider I'm talking about is in your region and uses the same encryption as Sky NZ but it's not Sky.

Maybe now you can see my hesitation in mentioning it by name on a public forum.

 

I'm just trying to rule out some known issue or some setting I missed, like the "VU+ Solo2 CI High Bitrate" problem from 2014 I'm pretty sure that's been fixed in the drivers and images by now though. I flashed the work around anyway just in case didn't fix it.
