I do some Audio and some Video Editting.

I know CDs are recorded at 16 Bit and 44100 Hz.

What is 16 Bit at 48000 used for?

Is this what they used when they Recorded on TAPE?

So why don't they use this for DVDs?

Why are DVDs 48000 Hz?

the higher samples / sec gives a higher audio quality
The DVD has the storage capacity for the higher sample rate than what a CD does, so they make use of that extra space

ohhh and DVD audio sample rates are not fixed at 4800 sps, there are considerably higher rates used as well
