This is a bug - not all teletext code pages are dealt with correctly in 
dvbtextsubs (I think only English, Swedish and Spanish).  I will fix 
this before the next release.

The best way to use this xml file with mplayer/mencoder is to use 
dvdauthor and spumux to create a DVD structure on your hard disk and 
then play/encode that using mplayer/mencoder.  The README file included 
with dvbtextsubs should help you with that - it should be easily scriptable.

Alternatively, you could write a script which converts this XML file 
into one of the many other subtitle formats supported by mplayer, or add 
support for this XML format into mplayer.

Hopefully future versions of mplayer/mencoder will support DVB teletext 
subtitles directly (i.e. perform the same job as dvbtextsubs internally).

If you cut the VDR file first, and then run dvbtextsubs, then hopefully 
the subtitles should still be OK.  I haven't tested this though.

What isn't dealt with is if you cut commercials out of a VDR recording. 
 I'm assuming that this results in (for example) a 4 minute jump in the 
Presentation Timestamp (PTS) values in the resulting stream.

Dave.
