no jeece. even if you could download it that fast your hard disk would never keep up. the fastest hard disk would never keep up.
also you need to be aware when they say "whole movies" they are most likely talking about rips, a movie re-encoded using Divx, MPEG4, or some other compression.
a whole DVD movie is about 8GB, impossible to download in 5 seconds. only a freak with a masive SCSI RAID0 setup could even hope to come that close.
