This is a hard one to put into words, but I will try. I have not had a chance to mess with the DVD much yet so this is mainly with the HD cable.

Last night I was watching a Blue Angles special on Discovery HD. It was like I was watching non HD TV. The planes just looked like blue airplanes. You could not see the detail in people's face like you normally can with HDTV. When I took the 990 and the 6 foot input cable out of the signal path (25 foot cable still in the path), the picture was back to sharp. You could see the shine on the airplane's paint, the detail in people's faces, etc.

So I guess I would say it looks as if the signal is almost filtered in that it lacks detail. I know the 990 is rated at 100Mhz bandwidth on the component, but it acts like it is not.
