When I got my PC from Dell, I got all the sound-cd-speaker bells and whistles. At the same time, I was getting the BBC magazine, which includes a cd with both music and cd-rom information with each issue. They would not play on my PC. The Dell technicians couldn't help. I still don't know what is in the cd-rom portions of the recordings, but the music tracks play on any old cd-player.

My daughter bought a Mac, and can't use my PC burnings of family pictures because I used write-protect. She is going to re-copy mine, but also said that a technician told her to use only Verbatim discs if recordings from a PC are to be used on a Mac.
