Then you won't care which format you get. It's like your computer: Does it have a DVD recorder? Any decent one will handle both DVD+R and DVD-R. These days most people don't even know which of those they're buying...
Wrong answer. AFAIK, there is not a dual format player currently on the market which is as good as standalone HD and Blu Ray players. Further, the one just announced from LG does not become available until February, 2008. And even more than that, this new player does not play interactive content on HD-DVD discs. The whole story, from MSNBC.
A Samsung model is not on the market until September, 2007.
Not being available is a perfectly valid reason, don't you think?
