When you purchase an HD video on a supported device or computer, only HD video will be downloaded. To download the SD version, you need to download the video again from your Purchased page. Conversely, if you purchase an HD video on an unsupported device, the SD version will be downloaded. Then, you will need to download the HD version from your Purchased page.

see... my point is that I am forced to buy the SD version at "THE LOWER PRICE". If I go to the iTunes download page, this SD movie will be in the process of downloading. I am not going to get an HD movie for a SD price. The problem starts from the purchase... or am I missing something?
PS... does this mean that I can download an HD movie purchased on my "New iPad" that is connected to my Mac by WiFi... and the HD movie file will end up in my iTunes movie folder???
