Is it possible to turn off the small window showing the current program while viewing the guide. I get so irritated when the mrs is looking through the guide for something to watch and then gets distracted by what's showing in that window. She can sometimes spend 10 minutes or more frozen to that window. Drives me nuts!
In answer to your question Push the Home key scroll to Help and settings and select settings then Display and subtitles scroll to video window and select Off your mini screen is then off if you need more help message me.
That didn't do what I was looking for. It turns off the mini screen while using the various Menu options, but it doesn't turn it off while the Guide is being displayed and scrolled through. It's this second bit that I was looking for.
