This is the first time i have tried to use it, and i'm having no luck- any help would be awesome.

I've downloaded a BRrip which my mplayer is too slow to read, so i've loaded the file into ffmpehX, and chosen target AVI DivX, mencoder mpeg4, then pressed encode, but the ffmpegX progress shows the file loading- but gives me no time frame, and I have left it on for several hours with no change to its progress report which is:
