AFAIK standard avi files have a 4 GB limit. There is a extension to the avi
format, called OpenDML
(http://www.matrox.com/videoweb/news/press/papers/odmlff2.htm), but it is
currently not supported by mplayer/mencoder.

I don't know how quicktime handle this though.

If you are working with large files make sure that you pass --enable-largefiles
to 'configure'.
