Could be. However I have been searching the web and still couldn't find info about bootleg 25 gig blu ray disc. All I found was the upscaled dvd 9 recorded close enough from a 720p resolution and being sold as blu ray kuno. To date this is still china and malaysia's preferred bootleg format (because the media is cheap). Ultil someone with a blu ray player tried it, we'll end up just speculating. Again, according to the seller it's the "original" and can be "returned" if not satisfied. It could be a new pirated mkv. format, original, or smugggled. Just out of curiosity if it's really a 1080p resolution disc with all the features of the original, then the industry is once again in trouble. I do not own a bluray palyer yet, but since my niece is an executive in warner brothers based in burbank ca., she brought me blu ray discs as pasalubong and she'll stop doing this if she found out I'm into bootleg.
Okay barrister! I am about to post when you posted first and found a website about this issue! It's now getting interesting...
