I am making a football highlite DVD. I imputed highlites from 4 games. Then a few days later I imputed highlites from 4 more games. I burned them onto a DVD. When I play it the first four games play perfectly but the next 4 are fuzzy. When I checked my file I can see that when I started adding the last 4 games it starts to compress all the files making them smaller. Any Idea why this is happening and how I fix itZ?
