General Operating System Information
-------------------------------------------------------------------------
On Windows computers, Samsung MP3 players require at least Windows XP
Service Pack 2. If you have an older operating system such as Windows
2000 or Windows 98, your computer won't recognize your player until you
upgrade your PC to at least Windows XP Service Pack 2.
If your PC is running Linux or MAC, it will not recognize some MP3
players that support only MTP mode. However, it will recognize players
that support UMS mode and list them as mass storage devices.
The following Samsung MP3 players support UMS: YP-U1, YP-U2, YP-U3,
YP-U4, YP-U5, and YP-S2.
The following Samsung MP3 players support both MTP and UMS mode: YP-Z5
and YP-P3.
Windows Vista may fail to detect you device if the player is not
connected properly, Windows Media Player is not installed or has become
corrupted, Vista is unable to install the MTP drivers, or the MTP patch
is not installed.
You can check it out further by going to this website and entering the information about your player

Samsung has a new version of Media Studio 5 available for download at its Web site. It isn't the exact model version, but seems to work.
