I bought a Sony DVD player. It played DVDs OK, but it couldn't play audio CD's I created from my PC. I returned this machine and I bought a Pioneer DVD player instead. These CDs play fine on this machine. In fact, these CDs  work on my car CD players, my computer CD players, and my 10-year old  Yamaha CD player. I was surprised that a new Sony DVD machine can't handle  this, since all of these other machines could. Maybe future versions will  correct this oversight.
