[MPlayer-dev-eng] Closed Captions sample found, Unknown user data. 05 0B, File uploaded.

[Tim U.]

I know the DOCS say that bug reports (playback problem in this case) 
should be reported to the user list, but one of the error messages 
displayed said "Contact MPlayer developers!" so I hope I did the 
right thing by posting to the development list.

I uploaded the first 15 MB of the VOB file to the FTP incoming
directory under a directory named "closed_captions,unknown_user_data".
I also uploaded a .txt (with basically same info as this message) and
the mplayer output with the -v option.

For the 20 seconds of the movie, and also later on in the movie,
mplayer displays this message a lot:

  "Unknown user data. 05 0B"

And the video is apparently skipping backwards every few seconds
during that time.

Then it starts to play perfectly and displays this message about two
times per second:

  "Closed Captions sample found! Contact MPlayer developers!"

Later on in the movie, whenever the "Unknown user data" is
encountered, it does that skipping backwards thing.  I just started
learning about MPEG, but to me it seems like there are two GOPs or
whatever for the same part of the scene, and you're supposed to know
which one to play (depending on the language or something).  That
would make sense where, in the movie, it is displaying "Hell House"
and "Hades" ('a' has an accento thingy),
but when it is displaying the "Dimension Films" logo, and in the
next scene where the back-skipping occurs, there is no visible
difference.  Maybe that "Closed Captions Sample" tells you how
to play only the one you want.  Hopefully someone can figure it
out.  I sure can't.
