1. Has the software been updated to use both processors yet? 2. How many M cards and tuning adapters does the XL4 need? (TWC RDU) 3. I currently have TWC whole house DVR, but it stinks. Besides the weak features, the DVRs and other receivers frequently fail to tune a channel and the get message that it's not currently available. Last night it was happening on several channels simultaneously, both HD and SD. I had always thought this was a symptom of over extended SDV, but a reboot seemed to clear it up (the TWC hardware needs rebooting at least once a week). Is "channel not available" common with the Tivos on TWC SDV? 4. Are there new Tivo models on the near horizon? I've used Tivo in the past and loved them, but the copy protection TWC inflicted killed the multi room feature, which is a big must have for us. I'm about ready to invest in the Premiere's, but I want to make sure there are no outstanding issues or new models worth waiting for.
