I have a Sharp LC45GD6U TV, and upgraded to the Motorola DCT 6412 III from Insight. I have a HDMI connection from the DVR to the TV. While watching a channel the picture will randomly go dark, ie. blank out for a second and come back on again. I tried rebooting DVR, jiggling the HDMI connectors and no change. Any idea what the problem could be? Note that with my older DVR with DVI to HDMI connector this never happened, so I doubt it is the TV.
