AVIAddXSubs is a simple to use, free program to incorporate subtitles (XSUB) from .srt file (ANSI text, up to 8 srt) or .idx/.sub file (containing up to 8 subtitles) quickly and easily to your avi files containing DivX/XviD video streams.
Just place the avi and its associated (same name) .srt in the same directory and Drag&Drop the .avi on AVIAddXSubs icon or shortcut in your desktop. In 2-3 minutes a new file with divx extension will be created and be ready to play.
I tried using this program today and it installed all well and done, however when trying to put the subs on a new video it created an error and did not work soo hence the programs fusing avi video and sub files does not happen.
