Bandwidth
do you use double bandwidth ? In other words if your streaming a video (1 gig) will you use this one time for your mac and 1 time for the stream (from mac to the apple TV) ? If so does this also apply if your using a hard line eg Ethernet ? I know that with the playstaion if you are streaming you get charged double bandwidth. I am curious I am currently looking into upgrading some desktops and laptops.
MacBook Pro, OS X Mountain Lion (10.8.2)
