I have a question regarding the 622. I just ordered it and I have an install date for Feb 21. I am currently Directv customer with a HD tivo. Does anyone know if the 622 has a name based recording (like Tivo) or a time based machine. Also, I got it for $299 without an 18 month commitment, an additional receiver for $49.99 with a $50 credit on my first bill and no install fee. Why would anyone sign an 18 month commitment if you don’t have to or did I miss something?
