Subtitles

Description

If I add three subtitles I get a error "Starting new cluster due to timestamp".
If I add less than three subtitles, it doesn't.
This error has existed for several years.
Some TVs have trouble playing the video with this error.

Test files:
https://www110.zippyshare.com/v/bJoDzEbV/file.html

Another bug:
During encoding of video the time on the screen freezes when the video has subtitles.
