Colorado based brick and mortar AV retailer Listen Up has posted an interview with Denon's Jeff Talmadge, Director of Product Development and Systems Integration.

In the interview Talmadge discusses the forthcoming Denon Blu Ray players, and states that Denon is committed to supporting both Blu Ray and HD DVD, and that a combo player ranks very highly on their list of priorities. However, of particular interest is when Talmadge lets it slip that Profile 1.1 Blu Ray discs may not play properly in Profile 1.0 players. All players and discs starting October 2007 will adhere to Blu Ray Profile 1.1.

To date all Blu Ray players are Profile 1.0, and unlike HD DVD, not all Blu Ray players are equipped with ethernet for firmware updates. If the hundreds of thousands of Blu Ray players now installed are unable to properly play discs that are manufactured after October this is a big deal. Three words: Class action lawsuit.

While it's been public knowledge that Profile 1.0 players would be unable to utilize Blu Ray's BD-J interactive features once they are implemented, if Talmadge is correct the troubled format may have even bigger problems ahead of it.
