hi guys! just chipped in to say, please please please wait for a few months before buying a BD player.
DivX 7 will release their new hardware DivX 7 Plus in a few months for the new BD players. that means you'll be able to play mkv and h264 formats without even thinking about converting them to a more compatible format for the standalone players! i hope you can appreciate how big a breakthrough this technology will be.
so, maybe waiting for a few months would make sense.
