yes this is true (replying to the thread to bump it up)
here's my thinking at present, please someone correct me if i'm making some false assumptions or just being stupid:
finder was updated in one of the recent updates, but the library DiscRecordingEngine was not (for some reason), so when finder tries to access the (new, updated?) variables _kDRDeviceMediaTypeDVDPlusRDoubleLayer and _kDRFlagsKey it finds them undefined and stops loading.
i'm assuming the library is not simply corrupt, since i tried replacing it with another i found at
http://www.macbidouille.com/downloads/MBDiscRecordingEngine.sitwhich resulted in the same errors (yes i'm pretty confident that i put it in the right place. and also backed up the original first).
so, is it possible that replacing the DiscRecordingEngine library with one that is up to date (10.3.6) from another computer would allow finder to load (or at least to the next out of date library)?
does the above make sense?
is there another solution that might save me the trouble of finding and replacing, say, 3 dozen libraries manually?
would replacing finder with a slightly older version, then trying to reapply updates work?
i've reinstalled windows more times than i'd like to remember, that i don't want to start doing the same for os x. not to mention the possibility of losing my girlfriend's settings/files, which would result in a black eye for me. (that's a joke. i swear)
any advice from someone who actually knows what they are talking about (as opposed to someone like me, who's just guessing) would be much appreciated.
thanks.
oh, also, i ran diskwarrior which fixed many things, but not the finder problem.
