However, you're going to notice some significant speed improvements with some of the newer instruction set extensions (I think MMX, SSE2, SSE4 and AVX made the most difference). I remember that I've read a ~20% improvement for AVX, and I think the previous instruction set extensions improved performance likewise. I'm not 100% sure though. For transcoding in MPExtended to work without stuttering, you'll need x264 to transcode at about 105% of the framerate of the source material (that is, if you want to play normal 25fps material, you should be able to encode about 26fps to avoid stuttering and have reasonable buffer times). (x264 is also the encoder used by VLC and ffmpeg, so the same applies for them).</blockquote>
