HD video performance on Mac Pro 4
It has done all of the software updates.
The only software loaded onto the machine so far is FCS.
Now when I try to watch The BBC HD video at 1920x1080 that I download to my local hard drive (vide from here http://www.apple.com/quicktime/guide/hd/bbc-blue.html ), it is very choppy.
IMHO, this machine should be able to play this video back in real time with NO issue. What do I need to do to correct this issue?
