Yes, the Slingbox will work with this TV source, you just need to connect the out of the VIP 1200 and the IN of the Slingbox (Audio and video), if you have component cables but you cannot get any video, take a look at this,
Thanks for checking in. I went for the $49 warranty and unlimited service agreement from SlingBox. Glad I did, because getting the settings all set up was not going to get done on my end. The cable connecting was the easy part, getting the settings re-established was never going to happen on my own.
