I had this discussion here a while back.
For those who think it cannot be done, if you go into your account and click on the button that allows you to choose your programming, it is one of the options.
If I remember the consensus correctly it was that you would not get the channels in the Family Pack in HD. You cannot get the HD add-on with the family pack (at least you could not at the time) so they were not eligible for HD. I too wanted the family pack for a variety of reasons (like the fact that the "bad" channels simply are not visible, you don't have to worry about industrious kids unlocking them accidentally), but alas, it was too good to be true.
The person who mentioned getting gold instead is correct from a $$ perspective, however I disagree wholeheartedly about the stupid part. I would do it if I got those channels in HD as well. It is *not* more cost effective to get Gold overall (Gold - 57.99 DishFamily with Bronze - 54.98), you just get more channels so on a channel per channel basis it's cheaper. However you don't get the benefits from the Family Pack which is really what I wanted. I just want those channels in HD too
