You can write a shell script and run it periodically via cron.  For 
instance:
#!/bin/sh
MAX_SIZE=4096000
DIR_SIZE=`du -s "$DIR" | awk '{print $1}'`
if [ "$DIR_SIZE" -gt "$MAX_SIZE" ]
then
	<SOME COMMAND TO BURN DVD>
	rm -rf $DIR/*
fi


You'll have to figure out the commands necessary to burn the DVD. I 
don't know that off the top of my head.  But that should get you started.
