Why mplayer in FreeBSD 5.1 behave not so good as Debian in my computer?

[zch]

Hi,
I have installed mplayer through cvsup while the error message, "your system is too SLOW to play this",always jump out. I had  recompiled mplayer with "without-runtime-computercheck", but the eror is still as before. While mplayer in Debian is well. And the two system audios are all oss drivered. Could anybody give some suggestion? Thanks!

Best wishes,
zhang
