When using XVideo overlay at DefaultDepth 16, on Radeon Mobility 7500, in an IBM T30 Thinkpad, 1024x768 LCD panel, the overlay is a blue rectangle.
The same git master build, has worked on Radeon 7500, Radeon 9200.
The following commands restore the overlay until Xserver is restarted
xrandr --output S-video --set load_detection 1
xrandr --output S-video --auto --right-of LVDS
sounds like an overlay crtc sourcing issue. Do either of the following commands also help?
xvattr -a XV_CRTC -v 0
xvattr -a XV_CRTC -v 1
