    I just replaced a Premiere with an XL4, and now if I step up thru the SDV channels I eventually reach a point where channels come up totally blank -- no error message, nothing. Typically it is every other channel -- if I go up one from a channel that works, or an odd number, no picture; up two or even, it usually works.

    Does this sound like a CableCard issue, or a Tuning Adapter issue. SA card and adapter on TW Rochester.

    I assume everything worked as expected on the regular Premiere?
    I hear the 4 tuner Premieres are more sensitive to signal strength and noise levels. Signal has to be split 4 ways instead of 2. On the T/A diagnostic screen, check the SNR level. I think it should be over 30. FDC should be no more than +/- 10. Closer to 0 the better. If those are out of range, call TWC to clean up the signal on the coax.

    The FDC was looking like -15, so I added a 15dB amp (with a reverse channel) and SDV acquisition seems faster now -- we will see how it goes over time.

    I know this is going to sound dumb and I didnt take the time to look it up but do you need 4 cable cards (two multistream) for the 4 tuner Tivo?

    No, a M card can support 6 tuners.
