I just purchased a brand new 52" Samsung LCD from Newegg (LN52A650). It's fantastic! Great colors and everything looks sharp. No dead pixels either. Anyway, I hooked up my frontend to the panel using VGA (HDMI cables are on their way as we speak). I have the color adjusted on that input so it looks better using the sudo nvidia-settings command. However, I've noticed that when playing ISO movies, the TV is showing 60Hz instead of the 24hz (24fps). I have been looking online, but haven't found anything conclusive as to how I can tell xine, mplayer or the Internal player to use 24hz. Someone said to wrap up the command (mplayer, xine, etc) in an xrandr script. Is anyone doing something similar to this now? Is there a generic script that will detect the native frame rate of a video, then pass that to the xrandr command which then passes to a player? I'm planning on purchasing a PCI 9400 from newegg ($75). Would this help in my quest for smooth, perfect video? Thanks for the assistance!<br>
</blockquote><div><br>mythtv, xine, mplayer etc.. won't change the TV refresh rate to match the videframerate.<br>using this patch: <a href="http://svn.mythtv.org/trac/ticket/5643">http://svn.mythtv.org/trac/ticket/5643</a> will help but there are inner problem when using nvidia card. nvidia drivers do not report the actual refresh rate but a unique value starting from 50.<br>
<br>As such, I updated those patches to be able to handle those weird reported refresh rate:<br><a href="http://www.avenard.org/media/Patches_%26_Add-Ons/Entries/2009/2/16_Match_refresh_rate_with_input_framerate_to_reduce_judder_and_nVidia_xrandr_support.html">http://www.avenard.org/media/Patches_%26_Add-Ons/Entries/2009/2/16_Match_refresh_rate_with_input_framerate_to_reduce_judder_and_nVidia_xrandr_support.html</a><br>
<br>If you search this distribution list, last month I posted the script I use for starting mplayer that does the same job: it will use xrandr to set the right refresh rate, then start mplayer...<br><br>Another thing to be aware of, if you're not using vdpau but Xv, do not do this. There's a bug in the nvidia drivers, when using a display at 24Hz to watch content at 24 fps, then X11 start using 100% of the CPU, and everything crawl to an end...<br>
