On the Home Theatre Forum, this has been discussed since
Casino Royale was released. However, NOBODY who reported the problem had a Sony player. The most common players that had a problem were Toshiba and JVC, though some owners of those players did not have a problem. Some Toshiba owners even got a firmware update and it still would not play.
The one player that seemed to do best was SONY. I think the article was being a bit overly glib by describing the problem with the SONY player. Sony discs are the problem, not their players. I have a Sony player that plays it fine.
