So try the attachment, unpack it in the box and restart the enigma. You should see YoutubeTV among Plugins. If it is there and you start it, you can end it by pressing the red button - which is used to turn off the box.
It's not my plugin, I'm not its author. I used to use it on Octagon 8008 before Chromium2 was on it.
I also don't know if it will work for you under OpenATV 7.3 and its python 3.11.x. So if not, don't be mad at me.
this work for dreambox dm900?
