Well... to be honest, Indeo is a somewhat old format (in fact I thought it had been discontinued - at least it's not available for OSX.) It doesn't incorporate the newer mpeg4 formats. And yes, mpeg 4 will show up as QT movies. So will avi. I'd suggest you search for DivX, & 3ivx , & XviD (click on links) & also http://www.gnutellaforums.com/showth...threadid=26816 might help. You WILL NEED these codecs so You might as well get them all. Good luck.
