I have my way to get the best in this world of limitations... really i pay very less and enjoy .I know the costs of the Blu ray discs are ridiculous,but trust me,with millions of people working everyday at the R&D's of the big AV companies,if there had been a slightest possibility of delivering such high quality BD images at a lower price,they would have done so.
The trust of buyers that the BDR are costly because they have high def images is based wrong assumption.
The polymer or what ever material used costly:No
Probably the content is taxed heavily , also this is another market manipulation game .
