Comment (by wonmanfactory):

 I further investigated the problem. Just a rough guess. Could the problem
 be that the TV station switched the subtitle channel to another channel
 while the video is playing?

 I attempted to compress the video and audio streams first, then subtitles
 stream individually and then combine them. I found that subtitles
 disappear in the midway. But subtitles remain in windows media
