since upgrading to OS X 10.8 I have several video playback issues.
I have a lot of videos ripped to my Drobo NAS, connected bij FW 800 to my MacMini (4 GB, 2009). Until recently, playback was smooth, either with VLC or DVD Player.
Since upgrading to OS X 10.8, DVD Player is not playing VIDEO_TS folders anymore, all I get is a chequered screen. This is also happening on my MacBookPro and my iMac i7, so this is not a specific hardware issue.
After upgrading to OS X 10.8.2, videos are playing back jerky and audio is out of sync in VLC and QuickTime.
Since I have 10,000+ videos in my library, this is absolutely unacceptable
I tried reinstalling OS 10.8, and trashing the prefs, but to no avail.
