Must be something different in your setup from mine; it doesn't work here. My cTiVo preferences shown below I download the TV show from Roamio to Mac via cTivo. I get a .ts file, a .srt file and a .txt file. Moving the .ts file back to the Roamio via McBrine pyTiVo and I get a working video file with audio, but there are no closed captions. Hitting the "info" button on the remote shows nothing in the CC field.
