One of the main improvements is in smooth playback as I can now properly match frame- and refreshrates. Watched a 1080@24p film yesterday and playback was supersmooth...UNTIL I loaded and started to render .srt subtitles. Every time a new line of text was rendered, the video would freeze for a moment. It seemed like the effect was worse, the more text was displayed.<br /><br />System is dual core opteron @3.4GHz, 6GB ram, Nvidia GeForce GT 210 /vdpau.

titles-cause-stuttering-video-audio-buffer-underruns-mythfrontend-0-24-a-14113/">this</a> thread, as I did mess about with the subtitle settings so I could see them on my older/smaller TV. I could check zoom settings, and live with smaller text now, but my CPU should be able to handle it as it is. The question tha t springs to mind is whether this might have something to do with frequency governors, and whether a more aggressive governor might help.<br /><br />Has anyone experienced similar and been able to solve it?<br /> </blockquote><div>What theme are you using, and what does its osd_subtitle.xml look like? There are certain effects that can be expensive to render, such as outlinesize, and if it takes too long to render the subtitle (or any other OSD component), you can get a dropped frame.</div><div> </div><div>Jim</div></div></div></div></blockquote><br />Thanks Jim,<br /><br /> I'll check and post the xml file this evening.<br /><br /> Ch
