Hi,
it didn't solve the problem, when I have a recording if I start to stream another channel the recording stops. Maybe is normal I don't know.
Thank you againfor yourfasr responses.

I expect that is a limitation of your provider. There are some stingy ones that only let you have one connection at at time.
Can you play more than one channel in your house at the same time from different Kodi devices? 

Yes, I can play different stream from different devices. For example I can see one channel from the iPad one one from the Apple TV. I’ve tried also to record a stream using another android application 

 Could you see if you can record from 2 streams at the same time on Windows from IPTV Recorder. Or Mac or Linux if you haven't got a Windows machine.
You can use the Task Manager to look for 2 ffmpeg processes.
