I've just run software update on my laptop - now runnning 10.4.11 and now
running quicktime 7.4 and all video capture has stopped in all versions of
processing error = I can't even run the examples - such as brightness tracking.

2008-01-31 15:04:20.168 java[276] CFLog (0): CFMessagePort:

'java.ServiceProvider'
See /usr/include/servers/bootstrap_defs.h for the error codes.

This happens when the update fails, or there is an old version of
QTJava.zip that's interfering with things. First look for a second
QTJava.zip file, and if you can't find anything, re-download and install
QuickTime again.

This is the only relevant part of the error:
java.lang.NoClassDefFoundError: quicktime/internal/jdirect/Linker
at quicktime.jdirect.QTNative.linkNativeMethods(QTNative.java:15)

The other stuff is Apple Java crap, discussed on the "platforms" page of
the reference.
