I have issues with EPG as well with this update.
This is for an X5 box using XC login . It gives me "No information" with EPG, and scroll to 8 hours later it has a few hours of valid EPG. Weird
I tried to clear EPG and change to "server" login and back to XML . Same thing . I installed Tivimate on this box and used same XC login . EPG works fine on Tivimate.
