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