lip sync problem when playing hd from pc

Hi,

I have a problem when i play hd from my computer to my plasma. I connnected my pc to plasma with hdmi( dvi to hdmi) When i set my pc resolution to 1920x1080 24 hertz the audio goes out of sync. My plasma is a pioneer 5090h, it should handle 24p. I have smooth playback of the video but the audio is getting behind. When i set resolution to 1920x1080 50 hertz the problem is gone but then i have no smooth playback ( 50 hertz vs 24 fps) Does anyone have a solution for this probem.

Thanks.

I've had a lot of problems in the past with ATI drivers and proper support for 24p. These days I just use Reclock to speed up 24 fps to 25 fps (pitch adjusted) and don't worry about it. 95% of my viewing is either native PAL (50hz) or 24 fps BDs or NTSC DVDs/downloads, which can be played back at 25 fps (50hz) with Reclock.

It's only the very occasional special feature on a BD or DVD that needs to run at 60hz now.

Hi, I have found that using reclock to speed up 24p material to 25hz causes judder, allbeit very slight judder that probably not everyone notices. Suppose I wondering if its possible to speedup from 24 --> 25 without experiencing judder?

Cheers,
