Ok, today I got the answer to my problem...thank all of you that suggested a fix, but today I went to the local Apple store and decribed what I had done, step by step...and immediately they had the answer.
I had downloaded an album from iTunes...and then tried to burn it to a CD to play on my home system not simply the computer. I got only mp-4 files that would not work. I had gone to the Library...and dragged the tunes to the CD I had on the desktop, and then tried to burn it...it seemed logical...but unfortunately not the way iTunes evidently works.
So with that I failed and received several suggestions as to what might be the problem. Nothing worked but it seems that was because I had not adequately provided the step-by-step process I followed.
So now...the issue was, first I downloaded an album...then in the Library I selected all the tracks, dragged them to a CD that I had put in the Superdrive...and then tried to burn....they burned, but only as MP-4 protected...which I guess is a data CD....no good for using in a DVD/CD player.
What I learned today is the burn must be done entirely inside iTunes...which means...once the downloaded tune/tunes are in the Library, first be sure your iTunes preferences are set:
Advanced>Burning>and select Audio CD option
Then you need to create a new playlist of the tunes you want on your CD from the Library.
Next, and perhaps this is unnecessary I highlighted all items in the playlist and then selected BURN-top right from within iTunes....I did that and BINGO...it worked. I have a CD that I can play on my home system. I have tried it on both a DVD player and CD player and it works perfectly.
I hope this helps all the other folks that posted to this thread.
And thank you to the several folks that tried to help...I now know I didn't give you enough detail to understand the original steps I was following.
Please feel free to correct any details that I gave that might eliminate a step or two.
