I've been having a few issues with my epg being out of sync etc., got up today and all the EPG data had gone except for free to air channels so I'm going to delete and start from new in case there is issues with the setup of the crossepg or something along those lines. My question is how to I completely delete it and start from scratch I noticed some people talking about putting the box to sleep which I don't have a clue about.

Many thanks

PS I'm running the latest image.
