Strangely, I have just tried to schedule 21:00 this evening on BBC TWO HD and have seen exactly the same "empty" "Programme details" dialog as Mihaid has reported.
I have 2 HDRs; humax1 (28073816) exhibits the problem and does not have the latest RS beta installed, humax2 (427573816) is OK and has the latest RS beta.
However, it is clearly not restricted to just Com78 as BBC TWO HD is on PSB3/BBC B. In fact, on humax 1 I can select any programme ony any channel and any day this week and see the faulty dialog.
Interestingly, the buttons available at the bottom of the dialog are correct; i.e. they depend on whether the programme is a series or already scheduled.
Anything that I can do before I update humax1 to the latest beta?
I have just had a look at the humax1, if has just recorded this afternoon's Triathlon OK (BBC TWO HD 14:15 to 15:15), but hadn't shutdown completely after recording had finished. The top item in its schedule is 12/8 21:00 The Handmaid's Tale, what follows is this evening's and tomorrow's programmes as expected. Both RS & WebIf show the Handmaid's Tale where expected in the expired part of the schedule.
