Decoding of HD streams requires more cpu power than decoding DVD streams because of the higher resolutions. If the cpu can not keep up, frames are dropped and motion does not appear smooth. With slower cpus we recommend video cards that support hardware accelerated mpeg decoding and the XvMC interface. Currently nVidia supports this in some of their video cards such as the MX series and FX4200 cards. Better deinterlacing can also be done on higher performance machines. We recommend systems with greater than 2.4GHz cpus to provide the greatest flexibility in the choice of video cards, deinterlacing algorithms and players with HD video streams. The MythTV project recommends a P4 3.0Ghz with Hyper Threading for smooth playback with their PVR software.
