Heheh, bro mikapoh reminded me of some friends a long time ago:

"This ahem dvd sure good one, got the Dolby and THX animations!!"

Then it occurred to them that the ahemakers can put in any animation from anywhere. Same as these BD copies - who can verify for sure anyways? In the end you'll end up in an endless circle, buying several copies of the same movie in the vain hope that THIS disc, this last one, will be the one with the definitive DTS track, or special feature...

I don't have a BD player, but I'm hoping to change that soon. I need my son to watch Planet Earth
