Demeter,

The "-ps" option of dvbstream requires exactly one video and one audio 
stream.  That is why it is failing to output a program stream.

You need to use the native transport stream (TS) format and then convert 
this into an elementary stream (i.e. mpeg audio) and play it using an 
mpeg audio player (e.g. mpg123 or madplay).

i.e.

dvbstream -o -f 12148 -p v -s 27500 336 | ts2es 336 | mpg123 -

"ts2es" comes as part of the DVB mpegtools.

You may experience some buffering problems, so you could try inserting 
the "bfr" program in the pipestream.

Alternatively, you can use my rtptsaudio program (available from the 
same place you got dvbstream) which converts and plays rtp-ts audio 
streams and do this:

dvbstream -f 12148 -p v -s 27500 336 &
rtptsaudio 336

Regards,

Dave.
