Query: Sleek looking, but ......

This unit claims to play MP3 discs, but it would not read the home-computer created CD-R or CD-RW MP3 discs that I have no trouble playing on either my Rio portable or Pioneer DVD players. I took some sample discs to a Circuit City store and tried them out unsuccessfully on a display model. Allowing for the possibility of a defective or broken display, I went to a second Circuit City store and got the same results there. They had a store-copy, commercially produced (by MP3.com) sample disc that worked just fine, but none of my Roxio or Adaptec burned CD-Rs or CD-RWs had any function. So, if you like creating your own MP3 compilation discs, and you're looking for a portable box unit that will play them --- this one's NOT for you!Also, there are no tone controls or equalizer pre-sets to choose from on this player. Except for the bass boost, one sound setting fits all.
