Might those logs in dmesg come from second graphic card? (RV370):

[18814.237220] [drm] 2: conflicting encoders switching off SVIDEO-1
[18814.237224] [drm] in favor of DVI-I-1

This card (on display :1) does not have S-video port:
$ xrandr -display :1 -q
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096
VGA-1 disconnected (normal left inverted right x axis y axis)
DVI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 708mm
x 398mm
   1920x1080      50.0*+   60.0  
   1280x1024      75.0     60.0  
   1360x765       59.8  
   1280x720       50.0  
   1024x768       75.1     70.1     60.0  
   800x600        72.2     75.0     60.3  
   720x576        50.0  
   720x480        59.9  
   640x480        72.8     75.0     60.0  

but my primary RV350 (with logs attached before) on display :0 has it.

Does "S-video disconnected 800x600+0+0" really mean that it's disconnected by
the driver or it's unimportant?
I've got problems with enabling S-video output before on UMS but there were
related rather to choosing TV standard or something else, but not load
detection (it said "connected" after --set load_detection 1 on UMS).
I mean if should I try to mix those commands in script many times (as before
I've did on UMS) to see anything on TV even if xrandr shows "disconnected" or
it doesn't make sense? ;-)
