Advertisements Have the same CableCards been used with both Tivo's? How many cards did they go through on your initial set-up? I had at least three bad cards when I did my initial Series 3 install. I don't think WOW has multi-stream cards, so I assume you have two single stream cards. Are the channels lost on both tuners simultaneously, or do they lose it at different times? Having the same problem on two Tivo's makes me think the cards could be flaky, but if the channels are lost on both tuners simultaneously, that seems less likely with two independent S-cards. This one has me a bit stumped... Edit: - you might want to check out this thread. Although a lot of the posters are from Cox - AZ, they do seem to mention Scientific Atlanta Cards, which is what WOW uses.
