Hi guys,i had install the mplayer from repo,and i had puted codecs file named all-20071007 into the /usr/lib/codecs,however i still can't see the rmvb files.i can hear the sounds,but can't see the video.why? i did the same things last time,and there was not any problem. must i replace the all-20071007 by window-all-20071007? what' the difference between them?
