Skips and Stutters

[dtcoates]

I just installed Microstudio and an MTU approved Plextor drive. When I import a CD track (from any manufacturer) the songs skip and stutter when I try to play them. Of course this can't be "normal" or no one would be using Microstudio.
System Specifics are:
Windows XP Home
AMD 2000+
768MB RAM (SIMM)
Radeon 9000 Video card
Creative Audogy Sound card
Plextor drive is Primary on secondary controller
(DVD drive is slave)
running Zonelabs ZoneAlarm and Norton Antivirus along with Creative's Disk Detector software

Anyone have any information on how to resolve this problem?
