I've found growisofs works reliably for me, using a Pioneer DVR-A05 
DVD-RW drive. 

    growisofs -dvd-compat -Z /dev/dvd -R -J -udf  /path/to/files/*
or
    growisofs -dvd-compat -Z /dev/dvd=foo.iso

I actually just wrapped it in a bash function that can either generate 
an iso image on the fly while burning it, or burn a pre-existing 
iso image: 

    dvdburn() {
        local BEFORE=$(date +%s)
        local DEV=/dev/dvd
        case "$1" in
        *.iso)
                growisofs -dvd-compat -Z ${DEV}="$1"
                ;;
        *)
                growisofs -dvd-compat -Z ${DEV} -R -J -udf "$@"
                ;;
        esac
        local AFTER=$(date +%s)
        local SEC=$[ $AFTER - $BEFORE ]
        local MIN=$[ $SEC / 60 ]
        local MINSEC=$[ $SEC % 60 ]
        printf '\n\nBurn took %d min %s sec (%d sec)\n\n' \
            $MIN $MINSEC $SEC
    }
