tv-out does not work after upgrade to natty

TV-out stopped working after upgrade to Natty. I suspect xserver-xorg-video-intel driver.

After plugging in the S-Video cable to computer and tv I see it is enabled by running

dg@bala:~$ xrandr
Screen 0: minimum 320 x 200, current 2304 x 800, maximum 4096 x 4096
LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 303mm x 190mm
   1280x800 59.9*+

   800x600 60.3 56.2
   640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
TV1 connected 1024x768+1280+0 (normal left inverted right x axis y axis) 0mm x 0mm

   640x480 30.0 +
   1024x768 30.0*
   800x600 30.0

But the tv screen shows nothing. I tested it on Windows and see that this is not a hardware problem. Also it used to be working in Maverick and before.
