Our Plex Media Server is housed on a Mac Mini (Intel) running Snow Leopard. It had no issues until very recently, when the version prior to Media Server 0.9.12.3 began to have some problems with playback.
Very occasionally, a movie called up via the Chrome web client (Safari has the same problem, FWIW) would start, then freeze at an open screen - typically one heavily artifacted - while the audio would randomly jump far forward in the movie, and keep skipping around.
It wasn't a common problem, and we lived with it. Following the upgrade to 0.9.12.3, however, it's occurring on two out of three movies called up all movies. Movies we know are available and formatted properly, and will play properly one minute and in the manner described above the next.
I've looked around in the forums, but every other reference I could find for skipping, jumping or similar pertained to video skipping some amount of time and then playing back properly. These videos won't play at all.
There's nothing else running on the Mac Mini, and it has been restarted with no apparent impact on the issue.
An example of the screen appearance is attached below, and I'm including a sample of the Media Server Log during which the movies failed which turns up nothing obvious for me. Any/all advice is appreciated, because for the first time Plex is basically unusable at present.
