Why does my recorder state that the EPG function cannot be used now? The Title List displays alright but not the Guide.Why?
1. Do you have the Digital Tuner selected (not the Analogue Tuner)?
2. Is the digital EPG guide selected in 'System Menu -> Basic -> EPG Type Select'?
3. Is the recorder plugged in 24/7 so it can receive EPG Updates?
Despite your 'digital tuner is selected', I'd still say you have the wrong input selected and that you have Line 1, Line 2 or Analogue selected instead of DTT.
My bet would be the GL has pressed the Input button one or twice and you have the Analogue tuner selected.
