Hello Yaobing,
Quite often I experience that the EPG in theater view does not display the correct shows. Instead it displays shows that are due 30-60 minutes later.
For example if the system time is 07:00 the content displayed in the EPG is from 08:00 or so. I especially experience it in the morning (before 08:00) but it is not limited to this time of day.
The EPG under Drives & Devices works just fine.
Let me know if you need anything.
Best regards,
Mikkel
