i have the latest Stretch and no folder lxsession in /.config
what now?

Sorry, I found it

Note: setting it in
/etc/xdg/lxsession/LXDE-pi/autostart or /etc/xdg/lxsession/LXDE/autostart

OK i do my best

I experimented a lot and read a lot.
This “streamurl is not defined” has made me curious.
So i put a new entry in the MMM podcast2.js under line 12 with:

var streamurl = '';

then it will work after a reboot, but not right after the first press.
You have to press again and next time it will come.
So page is set up, then Press Button for Play, Press Button for Stop, Press Button for Play and then comes the video. Very Strange.

The site has now fully built up.
Now i press the button: 
MMM-Podcast2 PLAY: < -- Nothing! Also do not wait for a longer time
MMM-Podcast2 STOP: 
MMM-Podcast2 PLAY: < -- now comes the Video
MMM-Podcast2 STOP:

Does anyone have a tip what this can still be?
For that I have no idea about the programming I am proud that I have managed it so :-) lol

OK i understand! :winking_face:

That leaves us mortals, only hope.
So bleibt uns Sterblichen, nur noch die Hoffnung.

Thanks for the information,
That means I can only hope and ask that the makers of the modules fix that? If that’s even possible!

You are in the wrong section!
Here are the “Show your mirror”

Did you do the manual or automatic installation MM before?

So I have do it and here is the log file.
