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.
