Guide data update

Wondering when and how often the guide data is updated. Is it up a dated once a day at a certain time. Thanks

The guide updates once a day usually. (I believe it usually occurs sometime during the 9am hour, but it varies.)

Sources using XMLTV guide data can set their update frequency to shorter intervals. Also, you can manually force updates to the guide database from the DVR server's web UI.

Thank you. Good info
