Are they exactly the same as the US releases? AV quality and extras wise? I ordered these from Amazon Marketplace seller iNetVideo and had no idea they would be canadian releases. They were fullfilled by Amazon, so I assume they're legit? I'm looking at the back cover of the Pirahna Blu and I don't see any mention of deleted scenes that the US release has....I don't want to open it to find out, because I may have to return it. I know there are a few canucks on here! Help appreciated!
