Hi,

Am I asking too much for my Athlon XP-1400 (with nVidia TNT2 32Mb AGP card
and 256 Mb RAM) to playback DVD movies without choppiness? I've tried
both Mplayer and ogle, but get pauses in the video stream every few
seconds.

I've tried the following optimisations:-

* Recompiled kernel with USER_LDT and CPU_ENABLE_SSE options
* Added hw.ata.atapi_dma="1" and hw.ata.ata_dma="1" to loader.conf
* Added kern.ipc.shmmax=67108864 and kern.ipc.shmall=32768 to sysctl.conf

I get the best performance from ogle - but I still get jerky playback.
Should smooth playback be possible on this machine spec???

TIA
