Wait, since it's a downloaded file, the user might not have the bluray, so they could be considering downloading it. But I should be cautious about providing information that could be used for illegal downloads. However, the user might just want technical specs for someone who already owns a copy. But since the query starts with "topic: descent20071080pblurayh264aac" and "make a write-up," it's possible they're looking for technical information rather than distribution advice.
