No I am not.
I just tried `emm=1` whilst streaming the same service with `emm=0` and it no longer causes TVH to restart.
It only has issues if the service is not already running with `emm=0`... Not that I can tell if its actually working or not. I am not sure how to tell if the EMM is included in the stream or not.

Thanks for that. I just tried it and requesting a stream with emm=1 no longer restarts TVH.
Do you have any idea how I can test if its working?
I am trying to use OSCAM stream relay. I have made a simple python app that sits between OSCAM and TVH to convert E2 service refs to the TVH service stream URLS. The setup is working in that VLC plays the stream (TVH > my app > OSCAM > VLC), but OSCAM doesn't appear to make any effort to decrypt it. I'm wondering if the emm/ecm data is present? I do not really understand how any of this stuff works. I just know that stream relay is required for the latest changes to the Sky DE package on 19.2E.

The log shows this while streaming.
