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

[zch]

Dear Kris Kennaway,
	  
1.Very Sorry for the so long lines. Because of I'm using the Foxmail and  
I don't know it will give so lone lines in the list.
	
2.the thing is true in the computer. I am install the VMware workstation 4.01
under Win2000 in a computer with 256M ram  and C1.7G. The virtual machines are 
FreeBSD5.1-RELEASE and Debian 3.0R1. I am install the mplayer in Debian directly 
from deb files and there may be the questions. I am just want to make sure of whether
my compile options are fit for the virtual machine and the better options may be selected.
Though I am sure the physical installation may be better. And I am just curious.
3.If you are still suspicious of this and I can post some snapshots.
	
Best wishes,
