Considering a brand-spanking-new TiVo Roamio Plus or Pro DVR? You might want to hold off a few months. Cable providers who haven’t provided updated firmware for their CableCARDs essentially limit 6-tuner DVRs to 4 streams or pixelate video beyond recognition. Out of the box, beyond the obvious viewing issues, customers in this situation may also end up with a certain percent of unusable recordings and will be unable to fully flex their TiVo Mini whole-home muscles. Yet, for those who find themselves in this predicament, TiVo has provided a method to limit the number of tuners in use until the issue can be corrected. At the moment, the dysfunctional 4/6 CableCARDs appear limited to certain Comcast regions running Cisco/Scientific Atlanta gear with the MSO anticipating upgrade completion in October. Further, FiOS TV subscribers with pixelated content and Motorola cards numbered ######-002 should contact Verizon for replacement.
The following CableCARD firmware versions are capable of handling six tuners:
- Motorola CableCARDs — version 6.25 or later
- Cisco/Scientific Atlanta CableCARDs — OS Ver: PKEY22.214.171.12401
Currently we have no data on compatible NDS or Conax CableCARD firmware. Nagravision CableCARDs can support four tuners only.
