Or you could use dvbaudio which also comes with dvb-mpegtools 
./dvbaudio
usage: ./dvbaudio [options] <pid>
options:
--help,     -h         show this message
--adapter,  -a  <nb>   set adapter number (default 0)
--ipacks,   -i  <size> set internal buffer (default 2048)
--demux,    -d  <dmx>  set demux (default 0)
--dvr,      -v  <dvr>  set dvr (default 0)
--frontend, -e  <fend> set frontend (default 0)
--freq,     -f  <freq> set frequency (default 0 = no tune)
--pol,      -p  <pol>  set polarisation (V or H)
--srate,    -s  <sr>   set signal rate
--fec,      -c  <fec>  set FEC (default auto)
--sat,      -t  <sat>  set diseqc nb. (default no diseqc)

and pipe the output into an MP3 player. You may have some trouble if
the player is unable to play at 48 kHz which will give you periodic
distortions depending on the buffer size.
