(1) I am running Windows Vista Business (Traditional Chinese Version) on
SONY VAIO, EVERY MP3 song warbles about few seconds before it ends if played
with Windows Media Player, but no problem with RealPlayer. How can I change
the player from "Media Player" to "RealPlayer" when I want to "Play All
Items" of that folder?

(2) Norton Internet Security 2007, Windows Defender, Microsoft Office 2007,
Adobe Reader 7.0, RealPlayer, QuickTime Player, FlatGet, Download Accelerator
Plus, WinRAR, Ulead Video Studio 8/Cool 3D, QQ Software, were all installed.
Every time when I explore pictures under a folder and want to "Play Slide
Show of all Pictures", Windows Explorer ends and restarts.

Please help. Thanks in advance.
