I have verizon fios and a Vizio 42" HD tv and if I connect the two using HDMI cables every few seconds or a couple times a minute the signal drops (screen goes black and audio stops) for probably about a second or two. Both the HDMI cables from verizon and a high speed set do the same thing. I can watch without problems using the standard coax but then can't enjoy the HD part. Does anybody else have the same problem or maybe a solution? Thank you.
