Comment (by wonmanfactory):
Hello,
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
