How to view/record multiple streams from a single Sat>IP Device?

[Profus]

Hi everybody,

I'm running NextPVR 3.5.7 on a Windows 8.1 (x64) HTPC with Kodi 15 as front-end. I receive DVB-S2 through a Telestar Digibit R1 Sat>IP-Device (which is the same as an Inverto SP-IDL 400, DSI 400 GSS.box or Triax TSS 400). Watching and recording TV works great both in NextPVR itself and via Kodi.

There is only one issue, I hope you can help me with: The Device has 4 tuners and is therefore capable of streaming 4 transponder streams simultaneously over ethernet to one or more clients. So I should be able to watch/record several programs at once. It seems to me though that NextPVR only supports one single stream from the device at any given moment - so simultaneous watching/recording and PiP work great whilst the programs in question are on the same satellite transponder. But if they are not, NextPVR tells me there is no free device available.

Is there any way to make NextPVR retreive multiple streams simultaneously from a single Sat>IP device? Or can I make it believe, there's 4 devices instead of one, so it doesn't stall as soon as I try to access a second transponder's stream?

I've been spending the whole day messing around with different TV Servers (MediaPortal 1 & 2, Argus) and NextPVR settings but haven't really gotten anywhere. So your help is much appreciated.

You should be able to do multiple. If it isn't, I'll provide you a fix.

Does it let you multiple recordings from the TV Guide for the same time, or does it tell you there is a conflict and you need to cancel one of the other when you try to schedule the second one?

Hi sub,

thank you for the hint. Scheduling recordings indeed works fine: I can schedule 4 simultaneous recordings via Kodi and 3 out of 4 were recorded just fine (don't know what happened to the last one though). Trying to schedule a fifth recording leads to an error message, which was to be expected. What doesn't work is watching live TV as soon as a single recording is in progress. When I try to do that in NextPVR it tells me "Unable to find available capture device", NextPVR itself doesn't allow me to schedule simultaneous recordings on different transponders either. Is there any way I can help to find out, what goes wrong?

Let me hunt out my Telestar Digibit R1 and see if I can reproduce.

I think I see what's happening. It looks like the device definition at http://<ipaddress>:8200/rootDesc.xml isn't including the X_SATIPCAP info with the Telestar Digibit R1. This tells the client how many tuners it has available. Without this NextPVR is assuming only one, so only one instance of the device listed on the Settings->Devices screen.

Wow, thanks for finding out. So it's a problem of the Digibit. There doesn't seem to be a way to edit the rootDesc.xml so I'll try to post an issue report to Telestar. We will see if they react. Is there any workaround I could use?

Not currently, but when I find a bit more time I could work on a way around this.

That would be great. Thanks a lot for your help!

the Digibit R1 provides this field wrong description ?

for SatIp should you find the right description under http://<ipaddress>:8080/desc.XML and the dlna one under http://<ipaddress>:8200/rootDesc.xml
there runs in the ssdp something wrong

ok i had look from where the Problem with the wrong description comes
