I just changed my time zone to one hour east. clock is off my an hour but EPG list ok. Since I'm in Nova Scotia, and Atlantic Time I had to choose Santiago Chile.
For people in EST and having an hour off change your time zone to america/halifax worked for me your clock will be an hour ahead but your guide is right
if you choose your correct time zone it is off by one hour.. read on another site.. that mfg. of software has not addressed this issue yet..
but it is a software problem...
All I do is hit the guide button (Next to the keyboard button) while watching tv and back up the guide an hour then look at it. Real easy. Guide works fine that way. I'm sure they will have an update for the box sooner or later.
