I found that mencoder is fast to re-encode divx file to smaller resolution in a good quality,and another benifit is that you can re-encode a rm file to avi when you are doing this in a linux system.
the output file is just fine when played in a PC,nometter linux or windows,but when I play it in my Z,I found it freezes mplayer in a ramdom time.I can use only ctrl+c to exit mplayer.
and I got no error message when this happened.
I try the mplayer from atty too.same situation.
any idea?

see here maybe the -rtc solves :

the -nortc option solves the problem.
many thanks.

say it again,mencoder is great!
I got lots of animations in rm format,now I can enjoy them in my Z.
