Ok on the iz3d drivers. Get the latest 1.10 from their site or the 1.11beta2. Disable antivirus during the install (select FULL install!) since some interferes with it. Antivirus can be enabled once the driver is installed.
When the driver is installed: Open up the iz3d control panel (i think you should have a new trayicon, otherwise launch it from Start-program etc...).
Click the "Directx"-tab. Under output you need to select the 3d-dlp or the ati-dlp (i'm using version 1.1 for now). Also check the "Enable stereo by hotkey" and press apply. You should be done now but eventually a reboot is needed.
If you now go to the "Help"-tab you should be able to click the left blueish iz3d-icon. This will start a testprogram to verify it's working. If it is then all good if it isn't, i don't know what to do.
The tv must be set in 3d-mode i believe. Sometimes some functions in tv's can mess up 3d so check the manual which settings that are appropriate.
Default hotkeys (all on the numerical board) during gameplay:
[*] toggles stereo on/off
[+] and [-] regulates separation
[Shift]+[+] and [Shift]+[-] regulates convergence
Separation sets the desired amount of depth.
Convergence sets the convergence. Easily (not correctly) explained this pushes or pulls the entire scene towards you. If everything has little depth regardless what you do with separation, then use convergence to pull everything towards you a bit.

Congratz on your choice! There's no way back to singleeyeviewing now.
