# description
#    A script to record a BBC AOD (Audio On Demand) stream from realplayer to MP3.
#    AOD URL:  http://www.bbc.co.uk/radio/aod/mainframe.shtml?http://www.bbc.co.uk/radio/aod/index.shtml?button
#    I date each mp3 I record, but this is not hugely accurate. 
#    This program is broadcast some days earlier than when I get around to 
#    recording it.

# * BBCsummary.sh  
# * audio-breezeblock.sh  
#
# mplayer options
# flags galore
# -nojoystick -nolirc - no joystick or remote control support
# -noframedrop  - don't try to keep realtime by dropping frames. 
#                 May only apply to video, I dunno.
# -softsleep    - use a pretend clock, not the rtc (RealTimeClock)
# -prefer-ipv4  - assume the network is IPv4, not IPv6 (eg. for DNS)
# -ao pcm:file=FILE  audio output driver to use. Redirects to file FILE
# -vc           - video codec. Turned off using dummy device null.
# -vo           - video output driver. Turned off.
