I noticed that Project-X is able to handle only subtitles within subID 
0x20. I have a recording with subtitles with subIDs 0x20 and 0x21 and 
demuxing fails with "command 248". If I restrict Project-X to subID 
0x20, I am able to demux that recording too. Unfortunately this means 
that the second subtitle stream cannot be demuxed. Is this related to 
the TODO Klaus has marked for 0x21 in dvbsubtitle.c?
