you need to increase the quality.
It's determined in two ways .... the picture quality (both pixels and number of colours (low settings tend to result in a picture which is made out of "blocks" of colour
and
the sample rate which "cuts" the action into a series of slices .... the fewer the slices the jerkier the fast action will be.
it's a case of balance
if you recode a dvd to fit a cd ..... (I often fit 10 hours onto a single dvd .... not brilliant ... but not bad on a small screen)
so a single movie on, at a push a CD should look reasonable on a screen less than 30"
more would need a dvd.
