For whatever reason I went to go check for a new version of Perian last night - the Swiss-Army Knife of Quicktime codecs - and it turns out that they're putting the project to bed. I absolutely understand that sometimes projects consume too much time but it's a bummer that such a handy tool won't be actively developed anymore. RIP Perian!

Guess now I need to find a way to make VLC look as native to Quicktime X as possible...
