I've read in a few places that the LG player isn't supported by de HD-DVD consortium. So it can't carry the official logo. I think it's because I doesn't support some kind of audio format which is compulsory to be able to carry the HD-DVD logo.
Still, its a great start, any pretty good value considering you get a 2 in 1 player for the price of most stand alone HD-DVD and Blu-Ray players!
