Epg is never excact. It is as it says a guide if the station is behind by 5 minutes the epg wont change. Its the same no matter where you get it from. I have my recording set for a pre record of 5 minutes and a post record of 10 minutes to allow for this. Change this options in media portal settings on the home page. Also you can change how many days you grab in the epg config from 2 to 7 if you wish I am grabbing 5 days at a time
