After few days of testing... I've reached the conclusion that finally the VLC team reached their goal:
Making Apple default Quick Time Player look like a better alternative than anything else on the market these days...
They even managed to fuck up the volume controls, now it's like driving on ice... you move the slider and 10 seconds after the volume raise or lower... animation is most of the time choppy... image quality below average... still impossible to play more than 1 movie at a time and they mimicked ITunes interface to include music and picture library. So now not only it screw up its intended purpose of playing movies but it can also screw up playing music and displaying pictures which is the last thing that was needed on Macs your are fitted with ITunes and IPhotos (like them or not, they do the job...)
