I've been reading through this whole thread to get some clarification on who needs this script and why. I think I've learned a lot, but not everything there is to learn.
Could someone please explain what exactly goes wrong by default? This is what I understood: By default, for 23.976fps content, XBMC switches the TV's refresh rate to 24Hz, instead of the wanted 23.976Hz. Did I get this correctly?
I'm using XBMC Live (the current stable Dharma 10.1 release from xbmc.org) with a Geforce 210 on my Sony Bravia, connected using HDMI. I didn't change anything with xorg or xandr, just enabled "Adjust display refresh rate to match video". When playing back 23.976Hz content, my TV shows: 1080p/24p. The playback is really smooth, except I get juddering for a few seconds every 40 to 60 minutes of playback. This always seems to occur in slow scenes, never noticed it in action (=high bitrate) scenes.
Now of course I'm asking myself if this might have to do with my content (=23.976fps) and my TV (24Hz) beeing slightly out of sync. Or would that cause more massive problems? Or is my TV maybe already playing back at 23.976Hz?
In the end, I'd like to know if I should run this script or not. I don't like to apply settings I don't understand, that's why I won't just download it and try. Maybe you guys can clarify this for me.
Thanks!
