Thank you for the interest in the Google TV and the Slingbox. With the Slingbox being to connected to the Google TV via AV cable you should be able to get what ever the Google TV is out putting. The issue is going to be how much control you will have over the device. If the Google TV you are connected to has an IR remote we should be able to get you a remote to control made for you if there is not already on in our data base. The only issue I will see you having wit this is the fact that there is going to be lag between your controls and the Google TV. This will make it extremely hard to interact with certain functions of that Google TV.
Hope this helps,
