Can a manufactured CD contain MP3 [or the MP3 format]?

Question

If yes to first question, would it need to be done [manufactured] at a slow speed., and then would it play on a DVD player?

Answer 1

Not all CD players can play MP3's, so unless it is a special promo CD, all audio CDs are usually in uncompressed audio.

DVD players are not required to play MP3 files. So unless a player specifies that it supports MP3 playback you will not be able to playback any CDs with MP3s

Answer 2

yes and no on the dvd player. cds are ment to play on PCs. every now and then thy come with dvds for doing just that.
