Tvheadend

Hi,

Before starting, here is a short description of my set-up:

There is one Tvheadend (version 4.2.8-36) instance running as an add-on for Libreelec 9.2.0 connected to 2 minisatip servers with 8 DVB-S2 and 10 DVB-T2/C2 tuners. All is working flawlessly with VLC as client, I can watch several channels on different muxes. However, the same case is not true when it's the pvr.hts addon.

For example, I'm unable to watch a TV show and recording another one at the same time. Here is a debug log illustrating the issue:

I saved the network traffic between the minisatip server and Tvheadend in a pcap file. In the attachments, I also put a screen capture of my configuration.
