u can try TMPG express 3.0.14 (although the latest is v 4.x.x)....divx files are not so easy joining, as the compression might be different or frame-rate or aspect-ration and also a number of other things, with TMPG express u need to reencode the files into DivX...newy the software is very user freindly so no prbs (only down side of TMPG is sometimes aud-vid desync occurs)
