Installation and Removal:

How do I remove Perian?
Open the System Preferences. Select the Perian pane and 'Remove.' Now 'Show All' preference panes, control-click the Perian pane and 'Remove "Perian" Preference Pane.'
Frequently Asked Questions:
Why does it take so long for MKV to load?
QuickTime expects to know about the entire movie when playing it, but that's not possible with many formats, including MKV and MPEG. Ask Apple to support seeking without an index if you'd like this to go away!
Is it possible to use hardware acceleration for H.264?
No — this isn't possible or supported in Mac OS X. Not even the AppleTV does it.
Will there be a version of Perian for the iPhone?
Unfortunately no, the iPhone does not have QuickTime. Since Perian is a third party component for QuickTime, we would need the iPhone to have QuickTime before we could get Perian onto the iPhone.
What if QuickTime for the iPhone ends up in a future update?
We are concerned that the iPhone, while a great device, is just too slow to play the type of files that you would use Perian to play.
