I've tried to convert my DVD's so I can download them to my iPad. No success. I received the Big Bang Theory Season 8. Inside there was a reference code for a free on line copy. I entered the reference code and the site gave me the option to open it in my VUDU account. I opened VUDU, there it was, under the My TV tab with two options. But it for $34.95 or Redeem. I selected Redeem and entered the same reference number. VUDU then said the reference number wasn't valid. So, I have the DVD there, but can't open it. Time to give up!
