Sequence editor adding audio (HD) Intel

Add Audio (HD) does not appear in Intel build ?

I have blender on PPC and Intel macs and on my intel mac (mac pro) it does not have the option for Audio (HD) only (RAM) which is not as good for other formats ?


Also why are there no audio output option on quicktime ? Animation codec via Quicktime is the best and yet if I want to output my edited audio I have to do it separately or do film as FFMPEG
