SORENSON was my thought at first too.but NO WIN 98 & ME DOESNT recognize the file as a playable movie....here's aht i didi and got it to work: 1) you've rendered the movie ( I actually used the SORENSON COMPRESSION ) in Poser for MACintosh....close POSER...you already have a working version of QUICKTIME ( NOT the FREE VERSION )...you then open yor movie and EXPORT as an AVI..seems like a pain, but i tried practically everything else.....
