Netscape Causes MP3s to Skip?

A member of the ubiquitous Clan Anonymous Coward asks: "Hi, I'm having some trouble playing MP3s smoothly on my PII333/96MB Linux box, running Slakware 3.6 w/ kernel 2.0.35. X11amp and mpg123 both skip when I scroll in Netscape. I have messed around with it a bit to no avail. Can anyone give me some pointers on giving the MP3 player a higher priority than other apps (in the hopes that this will keep it from skipping)."
