Well, there were twists, turns and false starts, but I finally had success with Badongo! Thanks! I uploaded a 700MB file intact, then, on second PC, downloaded the file in 3 parts, then used a "merger" file to sew them back together again, and the resulting file seems to play just fine! The cool thing, is I can give the link to the file (
http://www.badongo.com/vid/1413844 ) to my friend, and he can go through the same process. (There is another "buddy" process for downloading the file, but I haven't tried that yet.) I think we're in bidness....
