Doesn't NicePlayer also use the QuickTime engine? If so, doesn't it still have the MKV loading times?
I used to use Perian + QT, but opening mkv on network drives was a pain in the ass. Plus, the fact that I kept having to compile it from SVN in order for it to be remotely usable (QuickTime updates from Apple frequently break Perian and the expressions "nightly build," "beta," "backporting fixes" and "critical updates" don't exist in their dictionary) made me switch to mplayer.
Basically, they are upset someone posted a beta build to VersionTracker (or one of those other shitty sites that always show up in Google before the actual developer's site) a long time ago and now as a payback, they update less often than Debian Stable.
