Cdr-forum.de media information, is it affidabile?

while looking around, i found this site:
http://www.cdr-forum.de/index_dvdrohlinge.php

that from the EAN/UPC codes (barcodes) on the media, will give information about it (atip information), and also have lists of many cd and dvd media…

is it a good site?

The site has been known for years. Look around again, this time within the CDF borders.
