buddy,why take such a pain to make rar files and first of all,uploading 2.7gb is not worth it..try to make a divx or xvid or avi file out of it..even if u have nero,there is a program called nero recode in it( if your nero is version 7 or higher )..you can recode the movie to 700mb Mpeg-4 format..or else there r lots of programs on the net to make divx or xvid movies..
if u have the file in DVD formmat ( .VOB ),you can download DVD shrink from the internet( its a freeware )..reduce the size of your file and then upload..
