I did post this in the Test Build thread, but there's probably a bit too much "noise" there... So...
Can anyone explain to me how the various video configuration settings are supposed to work with OpenELEC and XBMC ?
Out of the box (ie no config.txt) XBMC decides to use DMA hdmi_mode=39 1360x768 60Hz whereas the screen (a Sony TV) is capable of doing 1080i. Forcing things to CEA hdmi_mode=5 1080i 60Hz displays OK, but with overscan (picture bigger than the screen) but regardless of what I use for the overscan_xxx parameters, XBMC appears to ignore them.
Using the video calibration tool within XBMC, I can get the initial GUI to display correctly, however those settings don't seem to be being used when I play full screen video - the screen is still too big. When exiting from full screen, the XBMC GUI becomes smaller than it should be, as if something's doubled up the overscan figures that got used when I did the video calibration previously.
Then, if I reboot, everything appears to be lost and I'm back to the GUI with overscan.
Any pointers ? I've tried various builds of OpenELEC up to and including 11315, and am getting the same issue.
