still struggling to get this work latest jester' SVN gives me something like this in the log:
19:43:20 T:90376 M:1072058368 ERROR: Win32DllLoader::Load: Unable to load C:\XBMC\system\players\dvdplayer\libass.dll (126)
19:43:20 T:90376 M:1072050176 ERROR: CDVDSubtitlesLibass: Failed to load libass library

19:43:20 T:90376 M:1072050176 ERROR: CDVDPlayerSubtitle::OpenStream - Unable to init subtitle parser
looks like the dll cannot be loaded? subtitle is in *.ass format and it doesnt work with or without refreshrate

Have you tried fullscreen?
I can only get subs working by launching with -fs and setting 'auto freshrate rate' off.

this doesnt seem to work very well for me. I am using the latest jester SVN which Catalyst 8.12 (ATI 4850) running Vista SP1.
I have my PC outputting to my Onkyo amp and then to my TV, if it switches refresh rate the output just dies and im left with a blank screen - though I blame this on ATI's drivers and crappy HDCP output.
When I had the PC hooked directly into my TV, it always reported a refresh rate of 60 (the output within windows). Even if I set the refresh rate as 24 within XBMC settings, the info on the TV would report 60, though pressing 'Z' whilst playing back would show 24hz output and change accordingly within XBMC though not on my TV info.
So what is really happening if my TV is showing 60hz but XBMC is showing 24hz?
Also got some strange results with the upscaling and auto refresh options selected, with the screen being off centre and unable to rectify it, disabled upscaling and it plays fine.

Your problem surely sounds like an HDCP thing, I remember threads on AVS regarding Onkyo and ATI.

I just have tested Rev16768, but the automatic refesh rate adjusting doesn't work for me. XBMC shows me all possible resolutions and refresh rate my setup can handle.
If I active "Adjust refresh rate" and press 'Z' during a 24p-Movie, XBMC shows me 1920x1080@24, but the info of my TV still shows 1920x1080@60, but if I set the screen to 1920x1080@24 and restart XBMC the TV info shows the correct value of 1920x1080@24.
If I select a new resolution/refresh-rate and than select "Test Resolution" the screen goes to blank for a second and after that it returns with the old resolution/refresh-rate. After a change I have to leave XBMC and after the restart the new resolution/refresh rate is active.
It seems to be the same problem dpassent has solved with v-sync settings, but for me it doesn't work.
For me it looks like there is a difference between the screen init on startup and a resolution change while XBMC is running.
Without 24Hz the video stutters and the TV-built-in 100Hz feature totally fails.
Any hints or tweaks?

try latest drivers - it started to work from 8.12 for me...

I forgot to mention that I have tested with 8.9, 8.11 and 8.12 with all vsync cominations in XBMC and CCC. And of course I have installed all vista updates.
The only difference is that with 8.12 I can select 24 and 23,98 Hz in XBMC.
And I have to correct my last post. If I change the resolution (for example from 1920x1080x60 to 1280x720x60) in XBMC and select "Test Resolution" the resolution is changing, but if I change the refresh rate (for example from 1920x1080x60 to 1920x1080x24) nothing happens except blanking the screen for 1 second. The refresh rate is still on 60 Hz after that.
Perhaps you can tell me your complete settings in CCC.
I think I have tested most possible settings, but perhaps there is one combination I haven't tried yet. Have you enabled tripple buffering when you turn vsync on?
- dpassent - 2009-01-01 18:04
I have EVERYTHING at default except refresh rate setting to always on in CCC. But I am on Windows XP SP3. I have vsync disabled in XBMC. ANd that's it. Be aware of subtitles not displaying after refreshrate change (it's a bug, reported, dunno if anyone is working on it). I have one more problem. Only 1st video file I play is smooth. Every file after that one is jerky. No matter if h264 or xvid, no matter what fps of the file. Exiting XBMC and running it again solves it but again just for one file... Anyone else noticed it?

+1, does anyone know the ticket number of the subtitle bug?

In my CCC I have -
Wait for vertical refresh > 'On, unless application specifies'
and in XBMC -
'Let driver decide'

thanks, i see it just got reassigned.
- dpassent - 2009-01-01 23:58
latest build from jester isn't jerky after 1st file, so this is the only bug that is preventing me from announcing XBMC as the greatest piece of software on Earth

Thanks. It didn't work, but I think it's an XBMC bug. If I set the refresh rate to 23,98 Hz the video is very smooth now and the 100Hz feature of my TV is working again. To let the driver handle vsync is the best choice for now, because the framerate in the codec info now are very stable. If XBMC handles vsync the rate is jumping from 23 to 25 Hz which ends in a jerky and stuttering video.
For now I can live with changing the refresh-rate evertime I want to look a 24 Hz Movie. I hope this will fixed soon.
