"Disable embedded subtitles" is not enabled by any chance?
(rightclick >) Options > Preferences > Subtitles [Subtitle properties]
Maybe a sample file or a link?
P.S.:
(1) If it concerns actual DVD-format downloads, please note only BS.Player
Pro fully supports DVD playback with DVD menu, DVD subtitles, etc! I'm afraid in
Free-version you can only
play the VOB-files.
(2) To be honest to you: I don't know if closed captioning is supported by BS.Player Pro. On the other hand I know that this feature was once requested by a user named "
reallife" and placed on the "wish list" (as well as "improved teletext for deaf persons") in October 2006.
