Ladies and Gentlemen, First, thank you for reading this thread. I apologize in advance if I make errors in my terminology. I am a Time Warner Cable Customer (with a tuning adapter) who recently upgraded from a Series 3 to a TiVo Elite. I am having problems with distortion on certain channels - VH1 by way of example - ultimately there are six of them that I have found so far. In describing the problem with the channel I have one of two issues (1) a flash of "pixellation" across the screen which can vary from a small amount up to blacking out the entire screen or I receive a message from the TiVo "searching for signal on this cable channel". Of note, I also have an external storage device - the Western Digital 500 gig drive. TWC has been out and has replaced the cable card, they have run new cable. Is it possible that the problem is caused by the DVR expander or the new TiVo? Any help is greatly appreciated.
