Recently lost 7 HD channels on my Premiere. Called Charter Cable and had them reinitialize the cablecard, but it didn't help. I tried restarting the Tivo but that also didn't help. I'm leaning towards the Tuning Adapter as being the problem but can't be sure, just hope it's not my Tivo. Either way I have to wait until Monday for Charter to do a truck roll to my house. Is it possible to get through a year without some sort of cable TV issue? Getting so sick of these type of issues!
