I have an HR23/700 box at release 0x87f
I record MLB games as manual recordings.
On Thursday 7/24 I set the following:
Start: 11 PM
Duration 2 hours 10 minutes
If during the game, it appears it is running late, I will change the duration.
If I change the duration before midnight, there is no problem.
After midnight, I changed the duration to 2 hours 40 minutes (the game was running late)
However, when I go to watch the game, it has the duration on the scale as 26 hours 40 minutes.
If I go back into recording options, indeed it was changed from 2 hours 40 minutes to 26 hours 40 minutes.
Here is where I think the error is made by the receiver:
When I edit it after midnight, it still has the "When" as Today instead of "Yesterday"
Even though it actually started the day before, it is adding the 2 hours 40 minutes to the 11 PM on Friday instead of Thursday.
I have noticed this same situation in the near past also. Usually getting a conflict with programs later in the day where my recording would already have stopped a long time earlier.
