I just came across this sd2xmltv project at github...I compiled the addon for Kodi...installed as instructed and voila! The addon generated an xmltv file from Schedules Direct for me. Of course, this will require having a SD account - but now you can pull the EPG info on the same system you're running LE on!
Here is the github link: GitHub - astrilchuk/sd2xmltv: A Schedules Direct to xmltv converter
Not sure why this hasn't been submitted to the kodi repo - but something worth getting added to the LE repo? I've submitted a note to the author as he mentiond that he was still working on the project and was going to enable icon information in the xmltv file.
If there are any questions on how I enable - let me know!
