I configure lirc to run a script when I hit the remote control 'power'
button. In that script:

STATUS=`ps -e | grep $PROG | grep -v grep | wc -l | awk '{print $1}'`

if [ `echo $DISPLAY | grep -c ":0"` -ge 1 ]
     if [ $STATUS -eq 0 ]
         echo "use mythconverg; update cardinput set startchan=1;" | mysql \
 		-u root --password=XXXXX
 	xrandr -s 1024x576 # AJB 20071104
         #( $PROG & )
         ( $PROG >/dev/null 2>&1 & )
         killall $PROG
         echo "use mythconverg; update cardinput set startchan=1;" | mysql \
 		-u root --password=XXXXX
exit 0
# try to fix problems with MythArchive mythtranscode sometimes failing
rm -f ~mythtv/.ICEauthority
