Always used HDMI on my Tivo HD. had to switch to component. What I noticed over component is that occasionally (say 3-6 times over one hour) there seems to be break in signal on component for fraction of a second. This is always repeatable, if I rewind and replay, the 'flicker' always repeats the same location. Most often it happens when there is a cut from one scene to the other (as in start of ads). It is not too obvious but once pointed out, we will easily notice. I never saw this on HDMI. TV is a 50in Panasonic plasma. Same behavior on 720p or 1080i. I haven't tried rebooting yet. Has anyone seen this?
