Update: Solved by installing missing libgtk, see below for explanation
Hi,
I'm having a rather strange problem with refresh rates which I fail to understand. To put it into a nutshell: Although the screen is properly switched to 23.976 fps to match the media, DVDPlayer detects a refresh rate of 50 Hz and subsequently falls over with audio discontinuities. I have 4 other installations of XBMC which don't exhibit this behavior, but they are on different hardware and have all been migrated upwards from older XBMC installations.
The key info:
Platform: Ubuntu 12.04.1 Server, i686
Install method: unstable PPA
GIT revision: 12.0-RC3 Git:7a6cb7f
GFX: GeForce 610 GT, Nvidia driver 310.19
Display: Denon AVR-4811 with a LG TV as monitor
To reproduce:
-- set XBMC initial refresh rate to at either 23.976 or 50 Hz (at 1080p)
-- play back any "24p" (23.976) stream
-- watch XBMC switch the refresh rate to 23.976 if it is not at that already. Confirmed with xrandr, xrandr-xbmc and also status output from TV
The IMHO interesting lines from the debug log:
Upon start of playback, the stream rate is properly detected and the display is switched:
21:35:01 T:2805988160 NOTICE: fps: 23.976024, pwidth: 1920, pheight: 1080, dwidth: 1920, dheight: 1080

then
