<P>AVI file playback works best on Solaris x86, because you have the
option to use the win32 codecs on the x86 platform, or can use
MMX/MMX2/3DNow/etc instructions for MP3/DivX/DVD/whatever. On Colaris SPARC,
you'll find quite a few AVI files with non working video and/or audio
playback, because the video/audio codecs using the Win32 DLLs are not
