Are there any players and tools that can view/extract subtitles/closedcaptions from TS files?

    I use DVB Viewer Pro (Windows XP Pro. SP2) to record and watch DTV
    stuff. It can record and show subtitles/closed captions (CC) as well.
    However, other players like K-Lite Codec Full Pack's Media Player
    Classic cannot show subtitles/CC. Am I missing something?

    Also, are there any tools that can view and extract them? Thank you in
    advance. :)

    This is a beta,

    I've used it after processing captured HDTV .TRP or .TS files
    through VideoReDo.

    The last few times I used it, the video and CC extracted
    subtitles grew out of synch, but Subtitle Workshop had the tools
    to fix it easily for all but one video.

    The author is asking for feedback, so give it a try and fill him
    in on your experiences.

    There are also a few fee based players which claim to support
    CC. I tried but one, which allowed no user configuration of the
    captions, before locating the CCextractor. If this gets working
    properly, I'll be perfectly happy with it.

    The player which comes with my capture devices indeed handles CC
    quite nicely, but loses this ability after editing with
    VideoReDo, when the captions become wildly broken, stutter,
    and/or flash on and off faster than my speed reading ability;-0)

    Thanks. I have used it before from ... It works,
    but I wished there was a program that didn't have to extract to SRT
    files since it takes a long time (over 20 minutes for a two hours video!).

    I did notice a problem with music note symbols: is
    a screen capture. SRT file showed:

    01:10:57,157 --> 01:10:59,191
    <i>[Marty] ¶ I don't</i>
    <i>know the words ¶</i>

    Is that normal?

    I use ProjectX to demux audio, video and subtitles from TS files

    I used that, but it was complex. I didn't know where to start. LOL.

    Download these screen shots - they may give you a clue to where to start -
    just remember I set these up for Australian Digital TV standards so the
    subtitle address won't be 801. ProjectX is a really great program and as far
    as I know is the only demuxer that corrects transmission errors as it
    demuxes and extracts subtitles. Also go to site as they have a
    section on ProjectX, I think also have one.. Good luck

    Thanks. Someone did send me those screen shots, but I was still lost.
    Heh. Oh well, I will just use the command line for now.

    Most other players use a different convention - subs/srt file
    extensions with text phrases referenced to specific time intervals for
    correlating when the player displays text the as letterboxes
    superimposed over video. Whereas CC is a streamed video transmission
    aside the primary material, optionally within a tuner's provision to
    simultaneously display. The file players then aren't transmission
    tuners at their basic function is the simplest answer. The tuner's
    allowable output for transposing a transmission into stored data,
    within what encoder conventions recognize, would seem an indication of
    how to fit CC into player provisions.

    Thanks for the ProjectX idea. It does not seem to work with the
    capture streams I get from the ATSC/QAM OnAir devices, nor does
    it work with the output of VideReDoPro after processing those
    streams. In the case of either, ProjectX does not see any
    subtitle or teletext content. It may be that a) it does not
    deal with multiple streams in a single transport file and b) it
    does not deal with MPG structures. Not entirely clear to me as
    it does play and demux audio/video from both files. Is this,
    perhaps, a DVB - ATSC issue?

    In the mean time, I'm hoping for an update to CCExtractor to
    improve its synch and dictionary.

    Sorry I didn't realise ATSC - this program was developed in Europe and works
    well for European, UK and Australian digital TV standards DVB.
    I guess it depends on the way subtitles are embedded in an ATSC signal? In
    Australia it comes up on page 801 and I think in the UK it's within the
    Teletext system - not sure about that. Maybe an email to the author or a
    post on might be of use. As a
    demuxer it's very good on original files from the tuner especially fixing
    timecode and other transmission errors. I do know if you pass the original
    file through VideRedo or Womble and output either a TS or MPG file then
    ProjectX can no longer extract the subs.

    The way I use it with my either my internal computer card a Fusion HDTV or
    Topfield 5000 SDTV PVR and BeyonWiz HDTV PVR I edit within ProjectX, top and
    tail and remove commercials then press the demux button and the resulting
    video and audio files I recombine as a mpg file in Womble. Then with the new
    MPG file and SRT file I can author a DVD if I wish. As I have done all my
    editing within ProjectX the subs are in-sync and as long as I don't do any
    further editing other than signal processing etc it all remains in sync

    The ATSC/QAM capture devices I use here, in SoCal, retain the
    subtitle in the recorded stream. The software player, which was
    delivered with the capture devices, will display subtitles while
    viewing "live" or recorded streams but has great difficulties
    displaying subtitles after the stream has been edited with
    VideoReDo. So far, the only program I've found which will
    extract the subtitle from a VRD post-processed file is
    CCExtractor. This free program is beta and the author seems
    willing to continue its development, given audience feedback,
    but there is much yet to be done.

    Among software players which I've tried, the only player I've
    found to display subtitles reliably, in VRD post-processed .MPG
    files, is Elcard's player. It's inexpensive, but lacks any user
    control over subtitles - such as size, font, color, opacity,
    background, or location. Upon inquiry, Elcard expressed no
    interest in enhancing their subtitle display.

    I've recently installed PowerDVD's HD player (Blu-Ray, HD-DTV),
    US$100. It does not see subtitles in these files at all and
    manages to destroy the NVidia drivers used by the capture
    software whenever I ask it to play one of these files.

    Telecast subtitles, while often desirable, remain a difficulty
