I have do here the same,have changed with E-Channelizer the referens of the most channels and now I have directly EPG and Picons,but I have do it only with my favorits IPTV Channels(Italian and German),for all other channels is to match work to change all the referenz.There are a few plugins too,that they convert the referens,but they don´t works for all iptv channels,so is it better to change it via E-Channelizer.
Do you have a video tutorial of how doing so?
and can I do it with the free version?
