In other words, it's like getting a malware infection on your computer that stops your computer from working properly.
The Wikipedia link posted above has all the details, although some users have been inserting a lot of technical jargon. You should still get the idea though if you at least read the summaries and such.
Yes, Oppo has no choice, all manufacturers have to do this if they want their players to play commercial Blu-Ray discs. My post was not meant as a criticism at Oppo specifically. I personally feel they are the most consumer friendly company around and they make some of the best players, and I feel REALLY bad for them that they have to be forced into this "make the technology work against the users" kind of scheme. I'm sure they are equally upset about it.
