Finally something is happening with the Ogg Vorbis QuickTime plugin.
Today a post on the projects forum enlightened the future for Ogg
Vorbis on the mac platform.
publius wrote this:
Some profiling of oggvorbis.qtx indicated that the lion's share of CPU
time was spent inside, of all places, QuickTime itself - but being
called from BeginMediaEdits. The BeginMediaEdits/EndMediaEdits calls
were wrapped around AddMediaSampleReference calls, but the Apple docs
clearly state
(http://developer.apple.com/documentation/QuickTime/APIREF/SOURCESI/
addmediasamplereference.htm) that BeginMediaEdits doesn't need to be
called in this case. This patch rips out said use of BeginMediaEdits
and this speeds up Vorbis file loading by ~20x in iTunes. Enjoy :)

And then he pasted a patch for the qtcomponents project.
But the thing is, no binary available
Could someone complie a new binary with this patch, so we could
actually test it?
