Just upgraded VLC to 0.9. It's amazing. Awesome interface, full FLAC support, bugs are nonexistent so far, much better subtitles, great sync functions, the list goes on. Still horrible at 1080p, though, so I'm not removing the other crap yet. Support for external codecs would solve a lot of problems. :/
Also, does anyone know about an alternative for Quicktime? VLC's Firefox plugin is pretty crappy, and I don't want to install a program which asks me to upgrade it everytime I start my computer AND forces me to install the worst digital distribution platform in the history of technology, which decides to override all of your settings to prefer itself over VLC without giving you an option.
