I've got about 20 or so channels that are pixelated (Time Warner), pretty badly, most of them won't stay tuned in for very long, and end up going to a black screen. I've connected the coax directly to the TiVo (skipping the tuning adaptor, as well as removing the cable card), and the channels come in excellent (aside from the few that can't tune, due to no cable card being present). Once I re-connect the TA the channels still work fine, however when I put the cable card back in, they start to go all wonky (digitized, sound like robots talking, etc). I'm guessing this has to be (or could be?) something related to the cable card, since the channels work fine, up until I put the cable card back in. The signals on the channels are all erratic and go from 0-24-70 and anything in between - all other channels work flawlessly. It's channels in the "lower" range of channels, starting at 33, all the way up to 502 (certain channels in this range work, so its not a very large number of channels), but it is for example SpikeTV (which is on 36, as well as 216). The HD channel (1216) of SpikeTV works fine, but the other 2 "alternative" channels of it, are all digitized. I'm trying to get an idea of what it may be, before calling Time Warner, since they don't seem to have very many folks familiar with TiVo's in my area, and if it ultimately could be the cable card (again, I have no idea, since I'm pretty new to all of this), then I can just go get another one (provided it doesn't fail the firmware update, as the last two we tried did, so we ended up going back to the one that was working previously, but has/had the issue with these 20 or so channels). So, any ideas, or suggestions of what I can say, or try? Thank you.
