Command Line Divx encoder

Hi I want to write a DOS batch file to run DivX/XviD conversions overnight. Does anyone know of any free utilities that can be called repetitively from a command line that will convert MPEG2 to DivX/XviD using command-line parameters? thanks

Hi! If you're using VirtualDubMOD for the conversions, you can use the included "Job Control" tool...

Thanks, but that won't do it. I think it requires you to use the GUI to set up all the jobs to be performed, then kick it off. I want to write a DOS batch file which will find files that haven't been converted, and kick off a conversion automatically, on a scheduled job overnight. I can handle the script, but I need a simple DivX/xvid command line utility that I can call in the form (e.g.): convert <file_in> <file_out> <switches - bitrate etc.>

mencoder can do that for xvid...

thanks I'll give it a go

Another option 

I use avs2avi, it can use xvid or divx. I run it with the -s -e params first to setup codec settings and store them to a file (useful for templates). then you can use a batchfile to encode your movies
