Small Q; tried several options, including reinstalling the ATV. I've read about several issues of the bcm70015 not showing up in XBMC, this is not my problem though; It shows up, but after some ffwd/rewind, stopping/starting/switching 720P movies (big bang theory, for that matter...) there seems to be a problem (stuttering, slow response from remote). At first the movie plays smooth, but when using it another point that day (or the day after) the same movie stutters like crazy. Smart installer has run, tried several (adviced) settings for video playback, but the only way to solve it is to reboot.. the kext files are added, they broadcom hd decoding can be selected in the XBMC playback.
ATV is now running 720P instead of 1080P, but the problem is still there. Updated everything, ran the latest update for XBMC etc, but the freaking thing needs to be rebooted every single time to enjoy the 720P movies.
Any help is more than welcome.
