Comment:

 I would like to validate the patch. There are no teletext subtitles where
 I live, so I downloaded some files with teletext magazine subtitles. I do
 not see any missing subtitle when I play it on current master. Can you
 supply a test file or tell me what to do to see the problem.

 TS Reader Lite shows this on two files I downloaded and the subtitles seem
 to be fine on existing MythTV master:
