Just to clarify the issue raised in this thread - audiojunkie is based in the Middle East so he's probably not referring to any particular location in Metro Manila.
Regarding Enemy at the Gates, similar to most local releases today, only the discs are imported from abroad. The label printing and cases are sourced locally so quality varies from distributor to distributor. This helps to bring down the cost.
Recently, some foreign studios have allowed Magna and Viva to replicate DVD9s here after the 2 largest local manufacturers were stringently evaluated & duly certified. On the other hand, Warner still imports 100% of its discs.
