Make sure that you try rebooting your TiVo to get the cards to update their channel map. If a warm restart doesn't work, unplug it and plug it back in. Both Cox and Comcast were kind of hanging back on the SDV thing (whilst TWC tears into it with a vengeance), with two or three test markets each. Cox has been upgrading from 750MHz to 1GHz bandwidth, so if they use it all for new HD services, they can add about 40 new ones before resorting to SDV (they can't use the new bandwidth above 870MHz for television programming to be received by either their deployed leased boxes or retail QAM tuners). They've just about finished their 1GHz conversion here in San Diego; I'd be surprised if they weren't doing the same up there in OC.
