Marta, what you are dealing with is standards. Some units do not play burned CD reliably this can be caused by the CD burning media or the chip used in the player to translate the 1's and 0's that the laser burns into the ink layer that burned disk's use for recording.
The standard is : http://en.wikipedia.org/wiki/Red_Book_(audio_Compact_Disc_standard) Not all manufactures follow the standard so a burned disk can have issues when trying to be played. The computer will work because a computer manufactory such as Apple expects at some time that a burned disk would be used. A stand alone CD unit may or may not expect a burned disk to be played in the player an so may use a chip set that will play Stamped disk's which is how bought from the store CD's are made using a glass master disk but will not play a burned disk. Also not all CD player will play Mp3 disk's this requires a more expensive chip set than the basic audio chip set and a lot of CD players do not include this or charge a higher price to compensate the use of the more expensive chip set. For a basic CD for a certain number of track's iTunes does fine. In your case they had to burn the file as an Mp3 file for it to fit on to the CD do to the size of the file. They could not burn it as a straight Audio CD due to the original size of the audio file. 740 meg bits is all that fits on a Audio CD and the mp3 file would be larger than the size of the CD after it is transcoded to the larger file size of the Audio CD format.

Sorry. This all has me so confused, and it drives me crazy when I can't figure something out. I don't do much importing from the iTunes store. They were always protected files and you could not even share one song with the friend over the computer. I rather bought my CDs and then imported them if I wanted them in my computers. So I never paid much attention to copying and playing on a CD player. But now I am confronted with making copies that play on an outside of the computer unit.

I guess I should mention that with importing the CD, it means importing it into my iTunes, I have no other means to burn a CD, but import and burn. In fact, checking out the way this CD came into iTunes is as MEG audio.
