<?xml version="1.0" encoding="UTF-8"?>Although each file was small in size (285 bytes, or a 4KB block for each file) the System Bloat was starting to add up. I have deleted 82 of these files without any problems. It appears that Apple was aware of this issue and has fixed it in Mac OS X 10.2.1, as the .plist files are not being created after I installed the updater.
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST

<plist version="1.0">

<key>dv com.apple.soundmgr._DV Sound Output Settings</key>

</plist>
So you may want to check your ~/Library/Preferences directory to see if you have a few of the extra .plist files.
