I record from dvb-t to mpg files. After chopping head and tail and commercials (cutlist generation), I do a lossless mpeg2 to mpeg2 recoding of the file to throw away the useless bits. (I was taught how to do that by SiHa in this useful thread: http://ubuntuforums.org/showthread.php?p=6394950 ).

Now for today's question. How can I do that without losing the closed captions?

Most raw recordings have working closed captions / subtitles that can be activated during playback by pressing T or by pressing M and picking the right entry from the menu. This facility disappears after doing the lossless transcoding mentioned above.
