Packaging Question

[pjpetrie]

Maybe there is a post already listed about this question but I couldn't find it, so here goes... I have a question about the packaging format of some UK releases. Specifically those titles from BFI or Eureka and a few other companies that release dual format editions. I have noticed at the top of some releases the packaging displays the Blu-ray logo in the upper left corner and the DVD logo on the upper right, and in some cases it's the opposite way around. Now that I am collecting only Blu-ray format packaging I am wondering if the company lists Blu-ray in the upper left corner then the packaging is a Blu-ray format size package and if the company lists DVD in the upper left corner then the title comes in standard-sized DVD packaging. Can anyone shed some definitive light on this question for me? Thanks, and have a great day!
