I've just purchased a TiVo Premiere (for use with OTA until Comcast cable is installed) and... I'm a little disappointed. I didn't come here to just complain though but instead maybe I can solve some of the issues I'm having. The first problem is that the channel guide (only available in SD resolution?) doesn't fit the full screen. Also, when I scroll up or down through the channel list quickly, the top or bottom channels turn black and it takes a second or two for the guide to fill them in. This is a bit disappointing because I like to scroll the channel list sometimes (by holding the down arrow, etc) and having lag and channels turning black is odd. Can anybody give me any suggestions?
