Recording -> no EPG-info file...?

Hi all,
maybe a noob-question:
How do I enable the recording of OTA-EPG information? TV recording runs quite fine, .ts files with windows-compatible filenames -> but missing .nfo/.txt/.epg-files.
I fetch EPG simply via OTA/EIT DVB Grabber, which is enough for me in Germany...
