cd players,radios,etc dont reconize my cd

[crispy]

Normal CD players as you describe will only play cds configured for audio. The data cd format is very different and is not meant for audio players (why would they need to read data cds??)

Have you tried burning to an 800Mb (or even a 900Mb) cdr?

By the way, some audio players have difficulty reading cdrs and cdrws.
