What happens with FIOS , HDMI, and native on is weird. The screen goes black for 3 seconds because the local insert is 480i, and the resolution has to be renegotiated. Then when the regular programming comes back, it's at 720p or 1080i so the screen goes black for 3 seconds after the commercial too, because the resolution has to be negotiated back again. Maybe the DVR simply doesn't know how to FF through these commercials because they are at a different resolution. I'll try to FF with FIOS tonight. But my point is that it's probably not a conspiracy, it's most likely a bug. But Laxguy is correct, more details are needed. Is native on? What resolutions are selected on your box? Does it still happen if you change the resolution settings around? Does it only happen on HD channels?
