Sometimes when my EPG gets corrupt it seems I can only continue by manually doing 'Menu' / 'Setup' / 'EPG' / 'Load-save-delete' / 'Delete EPG'
before starting EPG-Refresh 'Refresh now'.
Surely I should be able to acheive the same effect by enabling 'Flush EPG before refresh' in EPG-Refresh which I have always had enabled, as a fix for getting overlapping EPG events when the EPG is changed.
Something must be only half working in EPG-Refresh's 'Flush EPG before refresh' feature.
