The link you provide refers to TV programs recorded with windows media center, The original poster only asked about playing closed captioned DVDs.

Windows media center may very well include a CC decoder, I've never used it myself, but I know from experience that you can see closed captions on DVDs with windows XP pro/home (not media center edition) by following the directions I gave.
