hi, i have been downloading with bitlord. how can i get rid of a the white spots or der lines on my downlaod? i've been donloading movie files (700 MB) and i heard it is better to download a movie file form an actual DVD (4.3 GB). is that the problem? or is it my computer? are the files that are ca. 700 MB divx-files and the other dvd-files? or should i install some programm to make my pic better?
