Hm... I had that same problem at one point. I can't recall what exactly 
it was that fixed it, but it was not a problem anymore with this setup:

Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"
	VendorName  "Chaintech"
	BoardName   "nVidia GeForce 4 MX 440"
	Option      "RenderAccel" "1"
	# TV Out Setup
	Option      "TwinView"
	Option      "TwinViewOrientation" "Clone"
	Option      "SecondMonitorHorizSync" "30-50"
	Option      "SecondMonitorVertRefresh" "60"
	Option      "MetaModes" "1024x768, 1024x768; 800x600, 800x600; 
640x480, 640x480;"
	Option      "TVStandard" "NTSC-M"
	Option      "TVOutFormat" "SVIDEO"
	Option      "TVOverScan" "0.6"
EndSection


I want to say that it was the removal of the "ConnectedMonitor" setting 
that fixed it. Instead, I let the card auto-detect the displays, and 
the problem went away. Can't test it anymore though (at least not very 
easily), because I'm now just using VGA -> Component video (though 
under this setup, I can't ever use VTs; even the bios screen is 
scrambled, so nada until X loads, but the picture quality is worth it).
