So with the news of the upcoming external storage I guess it is time for me to start thinking about upgrading my receiver. I have a 522, but would love to have the external option with a 622 or 722. My biggest problem is my kids have TONS of shows saved and we don't want to lose them. Would there be a way for us to move those shows over? Does the fact I have bundled with at&t hurt my options? Please inform and discuss!
