I don't know why, but mencoder/mplayer apparently are ignoring the -sid
options and aren't showing anything, unless it is an embedded subtitle.
As a workaround for external subs, I pass an absurdly high sid (like
-sid 5000) and put -slave <<<sub_select at the end of the command line
to select the first sub. Your command would look like this with a
herestring:

mencoder "$1" -ovc xvid -oac mp3lame \
	-ofps $OFPS -sid 5000 -ass \
	-vf crop=$CROP,scale=320:-3:0:0:\
	$SCALER_PARS,expand=320:240:::1 \
	-sws $SCALER_TYPE \
	-xvidencopts bitrate=$VBITRATE:nogmc:noqpel:\
	quant_type=$QUANT_TYPE:pass=2:profile=asp3:\
	threads=2:max_key_interval=$OFPS \
	-lameopts vol=$VOLGAIN:vbr=3:aq=0 -o "$2" \
	-slave <<<sub_select

I did not actually do this with herestrings, I just used fifos since I
was using a lot of them already (I'm using mplayer as a frameserver for
x264). Try that if this doesn't work.
