Hi,
very late reaction, but maybe helpful for a solution.
I'm talking about the Grid EPG (Graphics) and am currently using Release 5.3.033, with skin Magic FHD.
I mostly watch Astra 19.2 (German) channels. Their primetime is 20:15 hr., but as I live in Ireland (- 1 hr), I always had that as 19:15 hr.
If I then pressed 9, the 19:15 hr Primetime starting time would be visible at the left, so I could see programming for the rest of the evening (Time-scale set to 300 min), which I have always seen as the logical behaviour of the Primetime setting.
From, I think, release 028 onwards (when primetime changed from 2 separate settings - primetime-hour and primetime-minute - to 1 setting Primetime), when I then pressed 9 in the EPG, it showed 19:15 in the middle of the screen, and the starting time on the left is actually 2,5 hours earlier (so 16:30 hr).
My workaround is to set Primetime to 21:45 hr, and that results in showing me what I had before, so 19:15 hr is the starting time on the left.
The same behaviour happens when changing back to the default skin VIX-Night-HD.
The time difference (in my case the 2,5 hours) is linked to the chosen Time-scale. I verified this when changing it from my 300 minutes down to 180 minutes. Without changing my Primetime (so still 21:45 hr) the starting time on the left now is 20:15 hr, so half of the chosen Time-scale.
I hope this info can help restoring "decent" behaviour to the Primetime setting again
Good luck,
Hans
