The problem may be due to the cpuspeed process, which is on by default in Fedora 8 and up.
What I have seen happen on CPUs that support speed throttling (Centrio, Core2, and others) is that the computer
is idling at a low speed when you start playback, and the player program uses the low CPU speed as a time base. Once the player gets going, the cpuspeed process increases the CPU frequency due to the higher load, and the time
base selected by the player changes, thus causing the playback to speed up.
Check if the cpuspeed process is running. To do that, either use
System->Adminstration->Services App, or, as root, in a
terminal window, enter: service cpuspeed status
If the system reports that cpuspeed is running, stop cpuspeed in the Services App, or use the command:
service cpuspeed stop
This will allow the CPU to run at its highest speed all the time.
Try your mp3 and DVD again. If that works, you can decide to permanently disable
cpuspeed in the Services App
