I'm running Tiger (10.4.1) on a 1GHz TiBook with 1GHz RAM. both 8.1 AND the new nightly builds (May 27 and 28) are doing these 2 things that make VLC unusable.
1) Randomly during playback of a bin/cue file, another video window opens but it will be blank, completely black. The movie continues to play in the first window. This additional window will be on top of the first window forcing you to click on the first window to see the movie again. Closing the new window makes ALL video windows close and stops playback. During the course of an hour of viewing between 6 and 9 new windows will open.
2) There is no audio when playback is begun, you have to go to Audio and choose Track 2 and then audio is restored.
