The problems with the A380 IFE were mirrored on my recent trip to SIN on QF A330's - but I beleive its different brand hardware, the problem sounds the same - either rebooting midway through a movie or just locking up.
On both flights the CSM added to his announcement not to press the buttons too fast or it would lock up.
But I guess it sure beats the days of trying to watch the projector screen on the bulkhead of the middle row
