Yeah the original patch is patchy but I don't think this patch is perfect 
either. Basically this picks off the first descriptor_tag. I did run a few scans 
to look for such a 'tell' but it isn't that easy. I hacked about the dvbscan 
util to tell me more info about the streams it doesn't know about (I can send 
you a patch).  From what I have seen yeah the audio streams have an 0x0A tag on 
them and they are easy to recognize. But the both the Audio and Video streams 
have the 0x52 tag on them (the audio usually has the 0x0A first though).  So the 
patch seems correct unless they change the order of these tags.

I think this would be much simpler done if the backend simply records all 
streams given in the channel description. The front end can then pick and choose 
which streams to play. This will allows you to record interactive content, 
teletext, subtitles... and then maybe later when viewing select the stream you 
want to listen/watch though the interactive interface or a manually cycle 
through all (suspected) audio/video streams.
