Yes.  I can't import my discs with just dd or the internal Mythtv
ripper, because they inevitably get I/O errors.  I use the following
script to rip them with dd rescue (on Ubuntu the package was named
gddrescue):
#!/bin/sh

if [ -z "$1" ] ; then
	DEV=/dev/dvd
else
	DEV="$1"
fi

DIR="/var/lib/mythtv/videos"

if ! DISCTOC=`lsdvd ${DEV} 2>/dev/null` ; then
	echo "Failed to read disc in ${DEV}"
	exit 1
fi

DISCTITLE=`echo $DISCTOC | awk '/Disc Title:/{print $3}'`
echo -n "Disc title [$DISCTITLE]: "
read NEWDISCTITLE
if [ -n "$NEWDISCTITLE" ] ; then
	DISCTITLE=`echo -n "$NEWDISCTITLE" | tr '[:lower:]' '[:upper:]'`
	DISCTITLE=`echo -n "$DISCTITLE" | tr '[:space:]' '_'`
fi

OUTFILE=$DIR/$DISCTITLE.iso

time ddrescue --no-split --verbose --block-size=2048 ${DEV} ${OUTFILE}
