Why is it that the opening credits (Stardock Logo), opening video, tutorial videos, and game play videos all skip. The video and audio feed plays for a second, pauses, then jumps ahead, plays again for a sec and then repeats throughout the entire video. Is my video card having trouble keeping up? My system and video card meet min requirements (My system: Pentium 4 - 2.4GHz, 2GB RAM; My video card: EVGA GeForce 6200, 256MB)
