The pirate DVD is probably copied into MPEG1 which has a far lower data rate than the native MPEG2. The DVD players you're using all use the CPU. A 900Mhz is OK for MPEG1 but it looks like it's struggling with the higher data rate. Most of the playback DVD in a very small window to manage it at all. What size are you trying to play it back in, full-screen?
Solutions? Either upgrade your CPU/Motherboard or buy a video card with hardware MPEG2/DVD support to take the load off the CPU.
