So, they said pretty much the same thing as Cox, which was that they were not aware of the product's requirements, and now that they are it will take time. -This is almost verbatim to what Cox said when the Premiere 4-tuner units hit the shelves. They even had to update their cards for the original 2-tuner Premiere, even though the TiVo HD had 2-tuners as well and could support a single M-card, or two S-cards (unlike the S3, which could only use the latter). Even if I don't own a certain TiVo product, I always contact Cox just to see what they say when I tell them how many tuners, and ask if they are prepared to support it. As a favor to the thread, I'm not going to start speculating on whose claims/statements hold water. I guess I'll hang-back and wait for the TiVo approved firmware to hit my existing TiVos, rather than put myself in the middle of yet another MSO/TiVo round of finger pointing, and running on fewer tuners than I paid for... What the heck happened, that the FCC, who had to approve TiVo's products, didn't see this coming, post cablecard reform mandate? Also, shouldn't CableLabs have been involved with both sides?
