Hi,
I just released epgsync-1.0.1 on http://vdr.schmirler.de. I've added a new option to schedule a resync every X hours and you may now use the SVDRP command "PLUG epgsync SYNC" to trigger a resync (this has always been possible by sending the SVDRP command to open the mainmenu, however that was undocumented and probably not obvious).
Have fun, Frank
