I don't think this is a TIVO issue exactly, but I am note sure. I have two HD issues. One is that when I switch to a HD channel the image size is much smaller than on regular channels. I don't see a way to change that in the TV setup. Is that normal? The second issue is that I view HD on Video 1 and there is a very thin line at the top of the image that almost looks like a line of highly compressed type. It is anoying. I can change to Video 6 and the line disappears, but then the video and audio are way out of sync. Any suggestions? Thanks.
