Sounds like you are playing back interlaced content on a progressive  
display, so you'll need to use one of the many deinterlacers to get  
rid of that motion blur. (Your TV does this for you when it's in the  
right mode which is why you don't see it playing directly to the TV.)   
Since it's an objective thing, the best idea is to play with each  
deinterlacer and see which provides the best picture without pegging  
your CPU.
