Stuttering

[DJ Unreal]

When I use Deamon-Tools to mount an image of a game, the cut scenes usually stutter sometimes; the same goes for images of movies mounted with it. If I burn the CD, I get no stuttering whatsoever, so it has to be Daemon-Tools. I've searched through the entire forum and it seems like no one else has this problem. Any ideas?

Defrag your hdd and check if dma is enabled.
