I was about to write "the critical difference between the Nagase player and the Buffalo player is that while the Nagase supports DivX playback, the Buffalo player does not."
BUT...
I was looking through the specifications again to make sure, and I found this line that says, "It's easy to playback movie files to your TV with a remote, such as MPEG2 or DivXR saved o­n the LinkStation, without using a computer!" So I'm not really sure whether or not it supports DivX, because the section above that does not list DivX as a supported format. o­nly XviD is listed.
If there's anyone out there who owns o­ne of these/can find out, please let us know!

Buffalo Corporation has announced that they will reduce the price of their "LinkTheater" network player, and 29 products including recordable DVD drives, o­n April 1st. The price list is presented without tax.

Affected products include 4 recordable DVD drive products, 9 internal/external HDD products, 2 network media player products, and others totalling up to 29 products.

The major point is the reduction of the LinkTheater "PC-MP2000/DVD" by 4,300 yen, bringing it down to 25,500 yen, as well as the same product packaged with a 120GB LinkStation NAS device, the "HD-120LAN/MPD" by 4,800 yen bringing it to 50,000 yen.
