This tutorial will show you step by step how to merge .srt subtitles with a .avi movie permanently using the free program AVIAddXSubs.

AVIAddXSubs is a small program (which you don't need to install) that allows you to combine SRT subtitle files with AVI video files to one file in just 1 or 2 minutes.
