running multiple sites from one instalation of CI on Media Temple

[eluser]tomcode[/eluser]
I don't know the Media Temple setup, but here a general setup :

Either with folders :
/www/
/site1.com/
assets/
index.php
/site2.com/
assets/
index.php

If You want to share the assets You need to create a sym link for one of the assets folders.

Or using different files :
/www/
assets/
site1.php
site2.php

with the in the index.php files :

Code:

$system_folder = "/serverpath/to/Your/system/";
$application_folder = "/serverpath/to/Your/application/";

then in the admin area of Your Media Temple account You point the sub domain entries to Your index.php (sitex.php) files
