Hi-def needs a lot of horses to play, I'm not sure about H264 compared to other codecs. H264 is designed so that specialised deciding chips (in mobile phones and set-top-boxes) can be built cheaply to aid playback, but on generic hardware I would imagine it would be a chunk more demanding than (say) the MPEG2 of the DVD standard written over a decade ago. If you mean 4 *processors* at 800mhz, then that's Pentium III territory, and you have no chance. You'd really be requiring a Core2 class machine. A Pentium 4 is likely to struggle. Video playback does parallelise, if the player is written for that. But 800mhz is still massively underpowered for hi-def video. Stroller.
