If you take a MPEG file and encode it to any format (such as divx), your result file will not have closed captions. This means that if you want to keep the subtitles, you need to keep the original file. This is hardly practical if you are archiving HDTV shows for example. - Subtitles files are small - so small (around 250 Kb for a movie) that you can quickly download them, or email them, etc, in case you have a recording without subtitles. - Subtitles files are indexable: You can have a database with all your subtitles if you want (there are many available), so you can search the dialogs. - Subtitles files are a de-facto standard: Almost every player can use them. In fact, many setbox players accept subtitles files in .srt format - so you can have subtitles in your divx movies and not just in your original DVDs. - Closed captions are stored in many different formats by capture cards. Upgrading to a new card, if it comes with a new player, may mean that you can't use your previously recorded closed captions, even if the audio/video are fine. - Closed captions require a closed caption decoder. All US TV have one (it's a legal requirement), but no European TV does, since there are not closed captions in Europe (teletext is used instead). Basically this means that if you buy a DVD in the US which has closed captions but no DVD subtitles, you are out of luck. This is a problem with many (most) old TV shows DVDs, which only come with closed captions.
