#5 Music distorts when using CD Rider

[Anonymous]

Whenever I start to rip a CD to my Hard Disk I try to
play other music at the same time. But when I do that
the music distorts into something hideous. Is this a
known effect of CD Rider? I'm using CD Rider 2.1 Beta 4
and the target I rip my CD's to is the same as the
source of the music I'm trying to listen to.
