Advertisements I have Time Warner Cable with tuning adapters. I also have a Premiere Elite (XL4) and a regular Premiere. I noticed a problem the last few days and am not sure how long it has been there. This happens on both Tivos. If you are in the HD channels (700-800) and if you surf channels by using the channel up or down on the remote some of the channels will not tune in. It is different channels all the time and if a channel does not tune you can't get it to tune if you use the buttons and select the numbers. As you scroll up and down some channels will not tune but as you come back to them they will tune in and maybe others will not. It seems quite random. It works fine on the "lower" channels. Can anyone else duplicate this? Thanks.
