no the difference is CSS (the encryption of DVDs) has been broken, but AACS of Blu-ray has never been broken itself. Cracking it relies on player keys being leaked and those are getting rotated in newer disks, that's what I was hinting at. They also do some ridiculous stuff with obfuscated virtual machines in BD+ and audio watermarking that may mute your ripped disk on newer TVs (I'm not joking[1]). So again: don't buy blu-ray either!
