Super Speed????

I just got epsxe 1.6 running on my PC and I could not be happier with this emulators performance. I do however have one minor problem that is bugging me. I loaded an ISO of "Metal Gear Solid : VR Missions" in epsxe and it runs great except for the fact that it looks like the gameplay is faster than it should be. Not a ton, but it is noticeable.

Does anyone know what might cause this or how I may correct it? Any help would be much appreciated.
