Onlocation CS4 playback sluggish
 

I recorded my first video event using Onlocation to my laptop. When I got back and reviewed the footage in Onlocation, the video took a couple of minutes to load, the audio stuttered and struggled to keep up with the video, over all it was very sluggish. However, when I played it using Windows media player or Premiere, it played normally and responded quickly. Note I'm using a brand new laptop with an intel duo processor, 4g ram, 500gb hd, Vista 64.

Mine stutters a little as well not really sure why.
