Radar,
Let me explain what I'm trying to accomplish.
I use build-in IPTV/kartina.tv (build-in IP address URL
Картина.ТВ , you can't modified it) - it works great, I have more than 100 channels, BUT it doesn't download EPG.
Several months ago, I found a solution for this problem - with FM 4717 you can modify the "IP address" field.
I downgraded FW to 4717, installed WEB Interface, installed a program that can get the channel list and EPG, and modified the "IP address" field to point to this program
http://localhost/m3u/playlist.php.
This program downloads channels and EPG with no problem.
Recently, I decided to upgrade FW to the latest version 5306.
With this version the "address" field is not editable anymore.
This is where I'm stuck - can watch TV with no EPG.
I think this is a file permission issue, but I don't know what file has the address field.
At this point, I see only one way to fix the problem - downgrade FW to 4717 as I done it in past.
Delete channels doesn't help.
