It was working fine up until the other week, I could play any DTS or AC3 with no problem. I went to replay a file and suddenly it just won't play AC3 or DTS and when I try it really messes up the system. When you launch a file with it it starts playing for just a second as the receiver changes modes and then things go wonky and the video freezes. The whole machine becomes sluggish. If you try to access the sound preferences you get a beach ball, open up a web page and if there is flash it won't load. Really weird.
Yet I can play the same files though Mplayer X with DTS or AC3.
I tried deleting prefs and upgrading to the newest VLC, no effect.
Any ideas?
