Comment:

 Mino, I'm not sure about this. I don't disbelieve your Shark observations,
 but:
 [[BR]]
 1. videoout_quartz.cpp doesn't actually use any CONFIG_* or HAVE_* that
 would enable/disable AltiVec
 [[BR]]
 2. It includes yuv2rgb.h, which defines the same functions regardless of
 config.h
 [[BR]]
 3. The header mythconfig.h, which is the same as config.h, is included
 before the first thing that uses CONFIG_*
 [[BR]]
 4. Apart from the user preference in videoout_quartz.cpp which can turn it
 off, the file yuv2rgb.cpp is really what determines acceleration
 [[BR]]
 If you have a patch (or gcc -E output or something), please attach
