I have a Buffalo LinkTheater (model P3LWG/DVD) which is the one that looks as follows:

There were a large number of firmware releases for this hardware. Each one seemed to fix some past problems, and introduce new ones of it's own. In particular some releases seemed to have issues with playing MP3 files. As a result users do not always want the latest firmware that was released.
The firmware releases were also split up between the European ones that included PAl support and the US ones that did not. I have a European LinkTheater and found I could use either the US or the European firmware releases, so I suspect the hardware was the same in both case. You need to use the European firmware if you need PAL support. these different firmware releases do not seem to be esy to obtain any more, and as over time I seem to hace accumulated most of them I making those I have available.
00-00-00.bin 01-00-00.bin firmware.htm etcThe .bin files are the various update files. The firmware.htm file is a text file in the following format:
<html> <body> <a href="00-00-00.bin" tvid="1" update>1. 00-00-00.bin</a><br> <a href="01-00-00.bin" tvid="2" update>2. 01-00-00.bin</a><br> ...Repeat as necessary... </body> </html>When you put in the CD you should get the playable file list. Select Firmware.html (this will load it ) and then select the link on the page.
| Use this firmware at your own risk as I will not be able to help you if the firmware update process fails. |
Note that if you want to "downgrade" to an earlier firmware release than you already have installed, it is likely that you will have to first isntall one of the Stepstone firmware releases and upgrade from that point.
