Comment (by weworama@…):
Hi, I am assuming that as this bug report has not been closed, you are
still working on it. Also that the code also applies to CEA 608/708
subtitles / closed captions on DVB-T recordings. If either is not the
case, I can submit another bug specific to DVB-T.
Our family has noted, in DVB-T recordings, all the same behavior discussed
in the original thread, although we have not recently noticed the problem
fixed in your patch.
In addition, some recordings captions are garbled/strange/poorly
decoded(?). I have posted a ~1 minute/ ~150Mb sample file
http://www.gigasize.com/get/two5x6jrn7b that shows myth seems to have
difficulty with 708 captions on recordings. The two srt files
(mythccextractor)
http://www.gigasize.com/get/mbft418ywmc 608 srtfile
http://www.gigasize.com/get/n005g7b2c0c 708 srt file.
This problem seems to cascade/include other behaviour, which might be
related, but I do not yet have a good sample for any of those.

Vlc displays the CEA 608 captions in the original 18+ Gb file, but
apparently didn’t recognize the presence of the second channel. The
posted portion was cut with avidemux, using the mpg ts demuxer as that
seems to be keeping the extra streams intact.
