Hello,
Kindly ensure your movie or DVD contains captions or subtitles. Subtitles appear on top of DVD videos, while captions appear below the video portion of Windows Media Video (WMV) files. If you're running the 64-bit Windows Media Player, you'll need the 64-bit version of DirectVobSub codec. This can be downloaded via http://www.free-codecs.com/directvobsub_download.htm.
You may try as well to change your subtitle file to exact name as your media name but keep the extension.
Example:
- 2 files are abc.avi and xyz.srt.
- Change xyz.srt to abc.srt.
- Now play the abc.avi in Windows Media Player. Right click on the playing window, check the subtitle setting.
