From what I understand from an email (regarding ordering the first patch on CD), you need both Service Release patches. I ordered the first patch on CD over a week ago, but never heard from them until today. Now they say you can get both on CD for those who have slow Internet connections and can't download it from their site. I'm assuming getting both on CD means you need both.
