I've tried using VLC on my Macbook (Santa Rosa Intel Core 2 Duo 2.4 GHz, OS 10.5.4) with no success. I download the disc image and drag the VLC application to my applications folder without problems. When I launch VLC the icon appears in the dock, bounces 3 to 5 times and then disappears, as though it has unexpectedly quit, but without an error message. I've tried this with a number of different builds and none of them seem to work.
The only thing that I think could be the problem is that I recently used a program called Monolingual that removes PPC components from universal binaries, as I don't need them having an Intel chipset. I haven't had any problems with any other applications and installing new ones.
Any suggestions?
