JediMakerXtream is dead - newer plugin is now called bouquetmakerxtream
Bouquet Maker Xtream - IPTV Bouquet Maker (new 2023)
A lot of people use xstreamity for vod and series, and JMX or BMX for live. Its entirely up to you.
You shouldn't have lost your bouquets - unless you had thousands and might have had a memory full issue.
Which is why BMX is better. You can choose just want you want. Categories and Streams
Can you use the same playlists. Yes. You can change the location of playlists.txt file in all the plugins main settings.
But... at the moment all 3 plugins create different epg importer files. They will all match up soon when I finally get round to it.
