If you buy or lease any ViP (211, 411 and 622) receiver you have to subscribe to one of the Metal Packages. You can keep the old HD package only if you stay with your current receivers. If you lease any of the above receivers you pay a $6.00 lease fee.
Here is quote from Scott's post:
"New and Existing customers choosing to upgrade to ViP series receivers (411, ViP211 and ViP622 DVR) must either choose to subscribe to a DishHD programming package with packages starting at $49.99 or pay a $6 HD Enabling Fee. Beginning on March 16th, customers who do not subscribe to a DishHD programming package will no longer have the option to disable the HD functionality on their ViP series equipment and pay no additional fees."
