If I do a TV show search in iTunes for Brothers and Sisters, its bring up Season 2 in HD - you can even preview it. But, rather than having a Buy button, it has "View Description''. When you press this, you are taken to the Show description, but the show is priced at $1.99 and is in SD -- not HD as in the Search Results. Anyone know why? Or how I can buy it? I'd like HD to match my Season 3.
