Hi guys!
This have been discussed before, but I haven't found a really good answer. It seems as it is impossible to get perfect studder free playback of 23.976 material with nVidia. Both me and my friend has tried for years, but the only way to get it studder free seems to be by speeding it up to 24 fps and therefore also modifying the sound somehow. Is it even possible to get right or is this a limitation with the nVidia cards and/or drivers? I love XBMC and don't want to replace it with some lame hardware player, so I really want to fix this. I'm really sick and tired of experimenting with xorg.conf etc, so it would be nice to know if there is any point in doing it.
Thanks in advance!
Use NVidia driver 302.17 and this xorg.conf:
http://xbmclogs.com/show.php?id=6030
It gives me the correct timings for 23.976 and 24.0Hz.
Check your setup by running xbmc-xrandr
EDIT: don't be confused by the codec screen. It tells you 24Hz for refresh rate and a speed of 0.001%. This does NOT mean that the video is played at higher speed.
Ok thanks for the info! I thought the codec info was implying that it was in deed upclocked to 24Hz, but it is not correct then? What vdpau settings are you using with your configuration?

On NVidia systems prior to driver 302.17 xrandr gave only rounded values and the value display on the codec screen is still rounded. Speed means the difference between the actual refresh rate and the value displayed.

What settings do you mean? Are you facing problems?
Hi there...
Will this work with ION1 Boards too? I got a Zotac ION F-Series.
Thank you

I mean for instance, should I still use sync playback to display with A/V sync or will it play correctly without altering the sound now then?

Sync playback to display is essential for smooth video. I have set A/V sync to video clock. You won't see any audio packets dropped if refresh rate matches video fps.
Ok, thanks a lot! Will give it a try!
how can we find the actual FPS of a movie file and the xbmc FPS when playing the movie?
Also, sorry if this is too newbie to ask, but I've added a nvidia PPD source and installed the driver, but its older than 302.17
I enabled the second version at the list (not the current one)

You need driver for Linux, not BSD.
xorg.conf link is dead.
