I'm still having issues, which isn't a surprise since no firmware updates have come out. Emptying your saved clips seems to work for a little while. Also doing something to jump-start it like taking a screenshot seems to help. But nothing is 100.
I don't doubt that this will be fixed eventually but I really hope it's sooner rather than later.
I was able to try it once today with BF4 and it recorded the 15 minutes it was supposed to, even though I was almost 2 hours into a session. I'll run it through its paces later and test it over multiple scenarios but I'm wondering if either 1.6 or 1.61 finally squashed this.
Wanted to upload a killzone match but it recorded something else (not the last 15 minutes).
It was actually weird because the "thumbnail image" was of the game I wanted to upload (at least the same map) but the actual footage it recorded was of another game on another map
