try this:

#! /bin/bash

RD=/dev/dvd

for i in 32768,7   32776,32 32808,32 32958,128 33086,128 33214,128 
33342,128 33470,32 33581,16 33598,16  33615,16  33632,16
do
 old_IFS="$IFS"
 IFS=","
 set -- $i
 IFS="$old_IFS"
 OFFSET=$1
 LENGTH=$2
 echo "*`dd if=$RD bs=1 skip=$OFFSET count=$LENGTH   2> /dev/null`#"
done

## end

(it's opensource ;)

Note not all DVDs or CDs store their info about autor title and copyright but some do, so try the script with some cd and some dvd and tell me if it works.
