As you have spotted the Humax wakes up at 4:30am every day, however it does this to look for new software NOT to update the EPG, this is usually not a problem because the Humax will look for new EPG data when it is woken from standby in order to view TV and also in the 15 Mins. before a recording if padding is not on. However this still leave instances (e.g. when you are on holiday and recordings are time padded) that the EPG may not be updated, the best way to get around this is to program a daily 'Reminder' (see user Guide >> Setting Reminders page 29) during the night say 3:00am to 3:20am. the daily automatic 4:30am wake is used to contact the Remote Server so they synchronise at least every 24 Hours, you can check when that last time your Humax contacted the RS at the top of the RS Home page where there will be a 'Last seen' time stamp in red. If the search information (e.g. Formula One) is not in the EPG on your Humax then there is nothing for the RS to find, the EPG for your area is updated by every Humax that is connected to the RS so even if your Humax doesn't contact the RS others will
