I am sick of the recording industry. I purchased 4-5 cd's last week. Ya I know who does that these days anyways I have a RIO 800 and wanted to load up some songs to play them on the Rio. I put them in the laptop to build the MP3's and you guessed it would not run. I wrote a article several weeks ago on how to make them work on your PC but a reader coincidentally sent me a link to a site that is a good educational read. http://www.fatchucks.com/
