Tvheadend

I've configured two XMLTV EPG grabber runs per day:

EPG Grabber -> Internal Grabber Settings -> Cron Multiline:

# Default config (00:04 and 12:04 everyday)
4 10 * * *
4 19 * * *

But with every trigger the XMLTV grabber runs twice. Normally not the biggest issue, but some services like www.epgdata.com which I use are limiting the max downloads per day to a very small number (i.e. 5). It's a pity to "waste" downloads in that case.
