From Rafa Gaitan, "I have corrected some includes of the quicktime plugin

from Quicktime/Quicktime.h to QuickTime/QuickTime.h.
MacOsX filesystem is normally case insensitive, but in 
my case I changed that option and the quicktime headers
were not found. Now compiles fine and on case insesitive
file systems should work correctly too. "
