It could be, I think twinview enables the nvidia driver's
internal Xinerama support. (With the nVidia drivers you
can use either the Xorg Xinerama, or nVidia's Xinerama
extension depending on the xorg.conf). If you compile
MythTV with Xinerama support you can configure it under:
on the second screen it will say:
Xinerama screen: [number]
Monitor Aspect Ratio: [ratio]
Set the Xinerama screen to 1 or 2 depending on which screen
is first, and set the aspect ratio to "16:9".
