This sounds like possibly confusing media formats with storage formats.
In general DVD and CD are the same shape but written very differently.
DVD players can read CD but not the other way around. CDs can generally
hold about 682MB of data while DVDs hold about 4700MB per layer. So a
dual layer DVD can hold about 9GB of data. Uncompressed audio on
standard CDs is usually in AIFF or Audio Interleave File Format and are
really big. So you can only fit 74 minutes on a CD in this format. It's
also the basic format that commercial CDs come as so many older players
will only play this uncompressed audio. MP3 format compresses down audio
files to about 10% of their original size or more depending on quality.
So you can store a lot more mp3 files on a CD than aiff files. Likewise
you could put mp3 files on a DVD and store gobs of audio. Some players
will play these and some will not. mpeg2 is the video file format used
on DVDs which also contain audio tracks and take up a lot of room. This
was why DVDs were designed to hold so much. Generally computers are much
more tolerant of playing audio files off whatever you've stored them on
(DVD or CD) while standalone players are a lot more picky.
Hope this helps.

It depends on the format being burned. For example, you can't burn
100 tracks of cd audio to a dvd, put it in a cd player, and mlisten to
tunes.
If you have an iso though, you can burn it to any cd or dvd that will
support the size. I've burned iso's of data cd's to dvd's when I
didn't have blank cd's handy.
If you had a very short dvd clip that was under 700 mb, you could burn
that to a cd and it would play in a dvd player as a dvd.

Listers is the technology different in a CD than what's on a DVD?
Meaning is a DVD just a higher capacity CD. Can I burn stuff to a DVD
and play it in a standard CD player as long as the media on the DVD
is in a format that the non computer CD player accepts?
