    has anyone seen a "teardown" of the Roamio similar to the one done on the Premiere, where each section was analyzed and the chips used identified?

    More commercial tear downs:

    First one got $170 for Roamio Plus material costs, which is the same number they got for the Premiere XL. They left off the Zenverge coprocessor, don't know what to make of that.

    The most interesting thing is the tuner is Broadcom's fullband capture with 8x QAM decoders. We might see a bump in features when CableCards are revamped.

    Cable cards revamped? That's funny. They will never be revamped. Done away with yes. Replaced yes. Revamped no.

    Ya, I intended that statement to be inclusive of Downloadable Conditional Access.

    These chips are not new. Here is the press release from June 13th 2011:

    There also is a 4 tuner chip which is probably what is used in the Premiere 4 models.

    The Cisco PKM908 CableCARD already supports 8 tuners:

    The Cisco Tuning Adapter with FW Version F.2001 also now supports 8 Tuners.

    I am not expecting any manufacturer to build and sell a retail 8 Tuner DVR, but at least Cisco did plan for that possibility.

    Premiere 4 tuner uses MaxLinear - MxL241SF (4 of them to be exact).
    Roamio 4 uses Panasonic - MN88436 (4 of them again).

    So the Pro/+ is the only Tivo device using the Broadcom FullBandCapture so far.
