Do you have a TiVo? If so your post in the TiVo forum would be better. I'm tempted to say that a video output setting of 576i and 1080i would be best but there are others who know better as it's been years since I had a TiVo. Also, the TiVo does not support UHD, so you'd need an upgrade to the 360* to get the best use of your new TV.
*requires VM's broadband as well
