Ogle plays fine on my P4-1.6Ghz laptop, though. Have you made sure that the DVD drive is using DMA? 'sysctl hw.ata.atapi_dma' will tell you, and can be set at boot from /boot/loader.conf. Also, I beleive that if you enable the SSE instructions that the mpeg2 and audio libraries that ogle uses will have to be recompiled to make sure that they generate the SSE instructions.
