Comment (by stichnot):


 It looks like there are two separate issues here.

 First, even though a recording is marked as having a teletext subtitle
 track, it can take an arbitrary amount of time before any such teletext
 data shows up in the stream.  Until that happens, if you attempt to switch
 to that subtitle track, you get the "Page Not Available" message (or a
 translated version of it, in your case).  This appears to be what is
 happening with the sample you provided.  The presentation of this
 information could definitely be improved.  For example, don't show the
 available of track information until the first packet arrives.

 Second, there must be something else leading to the behavior "Switching to
 Swedish channels often display a full-text teletext with the program
 underneath" originally reported.  Perhaps the track-to-page mappings are
 changing mid-recording.  Whatever the problem is, I will need to see a
 sample in which selecting a subtitle track brings up the full-page
 teletext menu instead.
