Has anyone downloaded the DFD file and used it to stream samples from a hard drive? Why is there a disclaimer on the download page? Does this download help or hurt?

I have a Toshiba laptop. It is a Pentium 4 with 1 gig of Ram and a 60 gig hard drive. I am using an ECHO INDIGO I/O soundcard. Samples load fine, but I still get a little hiccup once in a while. I only load the necessities on start-up. Can anyone share a bit of wisdom? Will DFD help me?
