In my MediaPortal, the EPG for Prime is one hour later than it should be. I missed the first half of the BOP/Otago match today because of it. It shows Prime News at 6:30. After a search I see that the complete opposite problem occured in April where Prime and all Sky listings were correct, but all the other channels (Tv1,TV2,TV3 etc) were 1 hour early for several days.
I hope they sort this out on Monday.
