I need a program to join wmv clips into a single file. I need 4 copies, each branded for a different site. The program needs to be a full windows install and compatible with windows me, xp and vista. The programs need to include installers so they can be used by clients. The joining must be seamless so if you need to write a splitter too to make it like this then LMK. The wmvclips are big 60mb+ and the final files will be big but below 2 gigs. I also need it done yesterday!
