[vdr] EPG lost after restarting vdr

Hi,

how to make vdr save epg data ? I use xmltv2vdr to retrieve epg database, so is need about 5 minutes to put in to vdr. Should always run xmltv2vdr after restarting vdr ?

the epg.data is configured to be stored in /home/.config/vdr/ with right permission, but no file created :(

Here cmd line: /usr/bin/vdr -v /home/Video -c /home/.config/vdr -L /usr/lib/vdr -r /usr/lib/vdr/vdr-recordingaction -s -E /home/.config/vdr/epg.data ...

there may be a setup that I ignored ?

Thanks.
