I expected someone to say that Finland DVB-T was the same as UK DVB-T.

I am probably not going to do any work on teletext subtitles.  Other people 
are working on this.

I think the most important thing to implement first is recording of the 
subtitles.  I've studied the subtitling specification, and although it looks 
complicated, I am confident of being able to implement it.  I also think that 
the DVB card's OSD should be capable of displaying the subtitles - obviously 
subtitles will have to be disabled when the OSD is active (that's how my 
"real" DVB-T receiver works).

Klaus - would you be willing to add recording of these subtitle streams to 
VDR?  The PES packets have the stream_id 0xBD (private_stream1) and would 
need a separate entry in the channels.conf file.  This would only seem to be 
applicable to DVB-T users.

I am happy to try and write the patch myself - would you accept it into the 
main VDR?
