Harry Potter would definately be a huge plus. I think that would be the tipping point for me being allowed to get an HD-DVD player, considering her cats are named after house elves. I already have her trained to not buy any new dvds that are on the HD-DVD release list.
Hopefully a second generation player is out by christmas. Maybe something that is less like a pc and more like a a\v component if you know what I mean. Additional audio codecs would be nice too.
