I noticed mine is using the firewire to attempt to read the input, not encode
from an HDPVR, so that would be different...also, noticed after posting that I
had some extra newlines in there...
$node=`(plugreport | grep 0x3c754afffeb53c7a) 2> /dev/null`;
# Attempt to record the current channel on the STB through the firewire port
system("(/usr/bin/test-mpeg2 -r $node > /tmp/$$ & VAR=\$!;sleep 1;kill \$VAR)
# If the output file is of 0 length, the box is off. Turn the box on.
if (-z "/tmp/$$")
system("/usr/local/bin/stb-command -n $node power_off");
