PIO4, programmed I/O tends to eat a lot of CPU cycles that would be better spent decoding DVD frames. There may not be much you can do about this though. 2. XFree86 3.3.6 tends to be VERY SLOW with bitblts. Try running top and see if XF86_SVGA is consuming a large % of your available CPU time (>5-10%). If it is, you may want to consider upgrading to XFree4 and installing the drm support for your card. It made a huge difference on my machine (full screen playback went from <1 FPS (at 1280x1024) to ~30FPS with CPU time to spare. Finally, has anybody else experianced the problem where xine only runs at 1/2 speed (even the audio?)? The latest versions seem to do this on my system, and I am wondering if it is a common occurance or a fluke on my system. -- _ _ _ ___ ____ ___ ______________________________________ / \/ \ | ||_ _|| _ \|___| | Jason Andresen -- jandrese@mitre.org / /\/\ \ | | | | | |/ /|_|_ | Views expressed may not reflect those /_/ \_\|_| |_| |_|\_\|___| | of the Mitre Corporation.
