What's up with that? My setup: - 2 working Series 3's with 2 cable cards each, they were working on the first try - 1 semi-working TivoHD with 2 cable cards The problem: - I get severe pixelation on one of the cable cards, it appears to be slot 1 (I determined this by unpluggin the card in slot 2, and seeing the pixelation remain). - When I test channels from the cable card menu, I don't see pixelation (although perhaps I just hit a good window) So, I tried to swap the cards (since FIOS doesn't actually pair them, I don't think), and I got repeated 161-4 errors when I put card 2 into slot 1. This also happened during the origina setup, with the tech here, so we started with the other card. The 161-4 error card seems to work fine in slot 2. So I can't test actually swapping the cards, since card 2 won't go into slot 1 without repeate 161-4 errors. Questions: 1) Is this repeated 161-4 error an indication of a bad TivoHD or CC? I doubt a bad card, since it should also be bad in slot 2? 2) Is the sever pixelation on only slot 1 an indication of a bad TivoHD, or a bad card? I doubt the latter, since the card should either work or not work? 3) Right after a reboot, thing seems fine for a while. Then they seem to progressively get worse. Any other experience with these problems? My S3's have had no issues, so this is new to me. Help!
