UPDATE2: Jim on TGB recommends for Windows 7 that you should use this version of mencoder and not the one I originally posted when I wrote this guide for Vista.
Rename mencoder-mt.exe to mencoder.exe and follow the rest of this guide.
UPDATE:
MrMarc on TGB forum, has some updated information about getting T360 working with Windows 7, see here.
Introduction
It seems there is still allot of confusion over Transcode 360 and how to get it setup properly, I've decided to write a new updated Wiki guide as some things have changed now since the last one here.
This new guide covers updating the mencoder.exe and ffmpeg.exe files, tweaking the MEncoderTranscoder.cs file to enable multi-thread decoding.
I also look at using Transcode 360 with Media Browser this time and talk more about local vs network setups with WHS.
Hopefully users can follow this guide and get transcode 360 working. The guide is based on a 32bit Vista Media Center setup, I've not tried this on Windows 7 lately but things should work pretty much the same way.
Use at your own risk and make sure you have a full backup of your system before you start.
You can see the new wiki guide here it's in PDF so you need Adobe Reader.

I maybe able to answer some questions but cannot give full tech support!
Good Luck.
