Anybody have any luck substituting a free HD Box rental for a Gateway Portal rental? I have a free HD Box rental listed at $5/month otherwise, and a Portal is also the same cost. They say they do no have a free Portal code, so cannot do it. Although, they tried locking me into a 2-yr contract to have free rentals - so it must exist. I wanted to buy a Gateway HDPVR, so would rather use a Portal than a free incompatible HD Box.
