Serving movies

[modD]

hiya all

i'd like to serve a couple of movies, but before that i want to know what's the best way to serve them- would chopping them up in rar files decrease the quality of the movie (divX)?

or is it better to split the files using some avi chopper without zipping or rar-ing them?

i have 128k upload so there won't be much bandwith to share

thanks!!
