I'm about to get D* installed on Tuesday and this is my first time as a satellite customer. I have heard there are many issues with the HR series hd-dvr's that directv has. Can I request a specific model and if so which one should I get? I'm really hoping that whatever I get does not have a slow interface and glitches as I'm moving away from one of the worst dvr interfaces I've ever had (atlantic broadband) and hoping for a significant improvement with the new service. Any advice would be appreciated.
