Sorry AlphaIVT...if you make it bin/cue, you're just making a cd image file (not really sure how you'd do this w/o putting it onto cd then ripping it off to bin/cue). Winrar will probably only be able to compress it <1% seeing avi is already compressed (and don't you think they'd compress it more if they knew how? ie winrar?). If it really is just standard AVI, maybe you could compress it to DIVX, but I'm guessing that's what it already is. You can d/l DIVX splitters though...
did that help?
