Re: why two settings for 640 x 480 and 352 x 240?

Ken,

The issue I answered was why 44.1 ks/s is used for CD audio. It is,
actually, based on analog video frequencies and frame rates...a fact unknown
to most.

They could have used any value for the head room, but chose this specific
number as it was connected to broadcast video.
