Well on my PII-400 with a Matrox G200 on XFree 4.0.2, I can get avifile (from the ports, I don't get the crashing problem you apparently have) to play Mpeg4 files fullscreen flawlessly, although it takes a good chunck of CPU time. The player will start to skip if I run a disk and cpu intensive task in the background (pan decoding large files for instance). Also, some of the non-Mpeg4 codecs in avifile don't seem to play right, however all of those codecs are supported by xanim now. -- _ _ _ ___ ____ ___ ______________________________________ / \/ \ | ||_ _|| _ \|___| | Jason Andresen -- jandrese@mitre.org / /\/\ \ | | | | | |/ /|_|_ | Views expressed may not reflect those /_/ \_\|_| |_| |_|\_\|___| | of the Mitre Corporation.
