moviemaker formats

Hello,

I use MS moviemaker to edit & prepare vids for later copying to a dvd, to
play them on my TV. When I 'publish' the edited vids to my pc I can save
them in 'best format for my pc' or 'dv-pal' .

The dv-pal format file size is 10-20 times bigger than the 'best' format. I
can see no difference between them on my pc monitor. Will it make a
difference when I finally copy them to DVD ?

Help pls.
