There seems to be very little information available for building MythTV on OSX 10.6, and the new version does not work right out of the box. If one finds it, it only works with MMX disabled, which then means HD stuttering. I hence had to go fairly deep to get it to compile with MMX. Here is the patch I have now to build it on 10.6.3 using osx-packager.pl (note that you first have to comment out --enable-libfaad in osx-packager.pl):

This also fixes LiveTV which is currently broken in trunk for OSX.
