osX updata?

[Jesper Nilsson]

Thats to bad that the apple guys cant do useful documentation and 
tech-specs.

Have been in contact with the people on apples Dev-forum? They have been 
very helpfully for me. Thats the place people goes when there is some 
info-lack in the documentation.

And I have to say that QuickTimes OnScreen functions isnt that good. But 
if it was quicktime-out supported then i would be more flexible. Like 
for converting to other formats etc. etc.
