Maybe you don't have enough cpu power anymore, because each core of
current cpu is slower than former single-core cpu?
What are exact names of old and new cpus? Does top show close to 100%
cpu usage when playing such files?

Other thing that can /probably/ lead to such results is timer issues.
I don't know if they can appear in your case, but updating bios and
getting newer linux kernel may help.
