For Picons there are several ways to fix and none is easy.
For UK picons and EPG there is a solution in Jedi Plugin read first post.
But for all other contries we have to be more creative ;)
Option 1
Use notepad and open your IPTV bouquets /etc/enigma2 with NotePad ++
Use Search and replace function in notepad (Kan be saved as macro for later use)
Search and replace all names like VIP FHD and simular with blankspace so you get the channel names like in Sat/Cable or Terrestial.
Save and reboot gui.
Option 2
Use E-Channelizer and download all settings from your STB.
Then in left window you have your Sat/Cable and Terrestial channels.
Just hold CTRL button and drag &drop the channel from left window into your IPTV Channel
and you get Picons + EPG id. You can filter your left window so you dont have to scroll so much
and you can also quick search left window for channels.
Save and upload your settings to your STB
Reboot Gui
Option 3
Same as option 2 only that you can use DreamboxEdit to do the same ;)
The only crapp with this is if you do an update or re create your bouquets you have to do it all over again :(
So we might have to figure out a way to use the swap function for UK channels so we easy can add custom channels also :)
