Perian’s swiss-army knife icon is a perfect fit for what the plugin does: turn QuickTime into the play-everything app on your Mac. The latest update has added support for compressed MKVs and a host of other things that, to be honest, I don’t really understand.
I believe that this added support should let me bypass VLC altogether for the playback of hi-definition MKV files, which is something I don’t believe it was able to do before (corrections to this post are sure to be swift and merciless if I’m wrong). If my guess is right, though, then there are fewer and fewer reasons to use VLC on my Mac.
It’s not that I’m against VLC in any way, but I like QuickTime X’s borderless window so much more…
