Thanks Hein, that helped. I copied the .xmltv directory to /home/hts and now it is pulling scheduling, but I think I may need to adjust the permissions and/or ownership of a file or directory that is incorrectly specified. tvheadend is not importing the scheduling to the EPG:
xmltv: /usr/bin/tv_grab_na_dd: Parsing completed. XML contained 21 channels, 4458 events, 0 new events injected in EPG
Suggestions are greatly appreciated.
