FYI - It looks like VIPER EPG has not being updated or maintained for the last 7 months. Since then many channels have been either changed, added, or deleted. Thus there are many 'holes' in the VIPER EPG. Have not looked at PACh guide.
IF you really want a complete guide it is so easy to use MC2MXL in conjunction with SCHEDULES DIRECT and pull your own guide. I pull 2 weeks of EPG and refresh every 2 weeks, rinse/repeat.
BTW Couch P - Is it possible to use your addon and point to my own guide instead of pointing to VIPER or PACh? I currently keep my guide on a USB thumb drive connected to a NVIDIA SHIELD and access it on KODI app.
