All I see you mention is aliasing problems while an image is panning.

I went through some possibly similar tearing issues with the LCD TV I'm using.
That plus audio sync issues. After taking the Revo and testing it on both an
HDMI computer display and on another HDMI TV in the house, I decided the issue
is with the TV itself and not with either Myth or Nvidia.

I contacted support for this Westinghouse WDE-SK-32H590D and they threw it
back at me claiming it was an "HDMI Handshake" problem. Whatever. At this
point I'm just living with it. I use MythTV's manual audio sync to set things
right. The tearing is at the top of the screen and only during fast horizontal
pans and so isn't too intrusive.

It's curious though that the audio sync adjustment is different between Myth
and mplayer. For Myth I need about -1500 ms and for mplayer I need about +200 ms.
