Answer 1

RW is rewritable. Don't use that unless you want to erase it and record over it again. RWs are not really meant for car stereos. Buy CD-Rs. Sheesh. Don't waste your money burning stuff onto expensive formats you have no need for.

Answer 2

You mean DVD+RW and DVD-RW.
The + and - designations specify the DVD format. One group of companies support one designation, while another group support another one. To keep things simple, the two different and incompatible formats are designated + and -.
Home DVD and computer DVD drives support both formats, but some DVD recorders only support one for recording.
You can store sound data like .mp3 on DVDs and a DVD has much more storage space.
Audio CD tracks are just for regular CDs. You don't write regular CD audio tracks to a DVD. Even if you could write regular audio tracks to a DVD, all the portable, car, and home audio CD players would not be able to play it.
Regular CD drives cannot read DVD discs because the laser works at a different wavelength and the pits & lands which make up the digital data is more densely packed on a DVD.

Answer 3

CD-RW and CD+RW are the same thing, marketing materials sometimes write them with a + and sometimes with a -. RW means ReWriteable. For the most part, these are readable in almost anything but are more expensive because they can be erased and written to again. Typically, they cost 3-10x as much and write at a MUCH slower speed than todays CD-R

DVD-R/RW and DVD+R/RW are two DIFFERENT formats. DVD's cannot be read by CD players - Both DVD's and CD's use red lasers to burn tiny tiny pits into the material the disc is made of, these pits (present or not present) represent the binary data (0 and 1) which computers use to store information. CD's use much larger pits and CD players are unable to read the much smaller pits used by DVDs.

So in short, your CD player CANNOT read DVDs with audio on them. A DVD Player can if the audio is in a format the player can understand.

New HD-DVD and BluRay DVD use even smaller pits and require a higher wavelength laser - a blue laser.

Answer 4

If a CD-R or -RW doesn't play, it's b/c the drive doesn't read it. It will only ready +R. Yes a sound recording can be put on DVD, but you won't be able to play it on your car stereo, only in a DVD player, DVD players might have the same problem, not all of them reads both -R and +R. It really is cheaper to buy a bunch of the write once R's rather than the RW's, unless you want to carry around only one disc to keep adding/removing files.
