I have a silver ONKYO 875.
I have a Scientific Atlanta HD-DVR going in to it via HDMI and component.
I have a PS2 going in via composite connection.
I have a JVC HR-XVC15S DVD/VCR going in via component and composite.
EVERYTHING goes out 1080P via HDMI to my 1080P projector.
I have NEVER EVER experienced ANY jitter whatsoever through ANY of the connections.
I have NEVER had any moire, dancing pixels, rainbow, or noisy/soft image problems.
I DO HAVE some very expensive UPS and power line filters and conditioners.
HD DVR, DVD/VHS, ONKYO 875, and 1080P projector are all plugged in to the UPS and power line filters and conditioners.
I use it for just about every purpose ONKYO intended it for so if a component is going to get hot then I have heated it up.
I noticed that the ONKYO 875 used to be pretty hot to the touch but over time I think it stays a LOT cooler to the touch then when I first started using it. Now it is just pretty warm.
I have about 200 hours on it.
