"Our own tests showed that some MP3 models including the YP-20s are not being recognized on the Vista-established personal computers (PCs)," a Samsung official said.
Other smaller MP3 manufacturers are also suffering similar problems.
Korean's ReignCom Ltd. said its H10 and a music player-embedded electronic dictionary model proved to be incompatible with the new operating system. COWON Systems Inc. reported that some of its MP3 players are not working properly on Vista-running personal computers.
Previous reportes also indicate that Apple Computer's music player iPod and its software iTunes do not function properly with the latest operating system, raising the incompatibility issue.
