Is there a particular reason why DVD playback is so choppy on Pentium M laptops (a 1.86 GHz model 750 chip in this case)? I tried xine, vlc and mplayer on Fedora Core 4 installed on a Dell Latitude D810 and in all cases the playback stutters. This machine has the ATI X600 graphics with the newest v8.16.20 driver livna packaged driver installed. I am quite surprised by this since even a 450 Mhz G4 with ppclinux could handle DVD playback smoothly leveraging the Altivec support. I assumed that the mmx support on the Pentium M would have provided as least as much performance but that doesn't appear to be the case. Jack
