I used to play some videos with subtitles fine. However, after updating my players, Some videos which previously are playing with subtitles, had not been showing subtitles. Any suspects? Need helps from all the masters.

Thanks in advance. =)

I used to play the mp4 files with Tiger Player, Media Player Classic but recently they can't seem to play the subtitles and only a player from Thunder is able to display the subtitles but it doesn't play smoothly.
