Can anybody help, I am editing DV in Media Studio, exported from a Sony DigiCam

I have got a 20 second clip that i have cut 3 seconds off the start and about the same off the end. I then create a DV AVI file, using the create option in the File Menu, which media studio does extremely quickly. However, when the video clip is played back in MS Media player it stutters and judders.

Is there anything I can do to stop this happening?

Thanks in advance
