Quality of Avi files played on Windows Media Player 10

I download avi files and play them in WMP 10 before I burn them so I wont waste a disk. On some files the movie is choppy. Not real good quality. Is there a way that I can tune my media player to have it in good quality. I got lucky on Napoleon Dynamite and Transporter 1, but Transporter 2 is bad. Where do I need to go in WMP 10 to adjust it? Properties?

Thanks,
Phil

 

the quality is only going to get better if the file you downloaded is of the highest quality.If the quality is bad then more than likely its not going to get better after you convert and clean it up
