Pixelating Picture

[carlosvic]

I have a question about my local HD reception. At least once a night one of my local HD channels will start to pixelate (if that is the right term) and I'll get patches of green screen. Most of the time I can fix it by switching to HDnet and immediately back but sometimes I need to reboot my system. Anybody out there know why this is happening.

I have a Mitsubishi DTV HD receiver (4 yrs old) with a roof antenna feed running through a diplexer.

Sometimes when the receiver loses the signal it will do this. On my Hughes E86 (I think the same unit) this used to happen ... even when I changed channels it would retain the image! As far as why I would say it is the same as MS Windows locking up and requiring a hard boot to reset it. I think the buffers fill up and the unit basically just craps itself.
