Hi,
Please read carefully what I wrote and follow it (bue indeed you can do the init 4 before then follow the process and end with init 3).
I read the beginning of what you wrote and I already point out a mistake: usersbouquet.iptv.tv (while I have written; userbouquet.iptv.tv).
So indeed if you do such mistakes this will never work.
Here is the file but editing properly the /etc/enigma2/bouquets.tv properly will remains yours.
Unpack the file and transfer it to /etc/enigma2/
(to unpack on linux: tar -xvzf ./userbouqet.iptv.tv.tgz)
I am not 100% sure that all the iptv definition are still active today, it was just a sample file that I create a few months ago.
Be also carefull that this inclusion of iptv into the channel list is working on OpenPli image and its derivated, I don't know if this work for all images.
