[mythtv-users] Widescreen and SVideo settings

Bumping to the top...

Does anyone have any guidelines or is anyone using a primary widescreen 
output while also outputting svideo? I want to be able to watch the primary 
widescreen display most of the time, but still be able to watch the svideo 
output on the bedroom TV. I don't need to do both simultaneously so I'm not 
really considering a second mythtv FE.

Problems I have:
1. Using nvidia twinview, I can get both displays working, but I have to use 
"clone" mode and this puts the svideo window in the center of the widescreen 
view like so (hope this turns out):

<-----------864 x 480----------->
= | | =
= |<-------640x480------>| =
= | | =

2. I can't get twinview to shift the center window (640x480) to the left, so 
on the TV display, the right half is cut off.

Any help would be appreciated.
