When buying HD TV shows off iTunes does it download the SD as well? And if so does it charge you more than $60? I just bought the HD version of Chuck Season 2 since I have seen Season 1 and looked at the download part in the iTunes and it has 44 to download. I noticed that is it downloading the SD as well. Is that really how it does it? I've bough Scrubs Seasons 3 & 4 before but those where just SD.
