I read about mplayer performance and saw that everyone is using -vo bvdd

However this gives me an error. I have installed mplayer -bvdd-iwmmxt on cacko 1.23(with upgraded firmware). Someone have explanation for this? sorry if it is noob question.

EDIT: I haven't installed the bvdd lib since i heard it is included in cacko, and since it isnt in the cacko feed. But i am running cacko lite so can it be that i have to install it seperately??

Well, you'll need the bvdd kernel module in order to get the video overlay acceleration of the PXA270. Not sure, if Cacko Lite already has it installed by default.
What kind of error message do you get?
If you type lsmod in Konsole, is bvdd listed in the output?
If it's not listed there, try to do a insmod bvdd.

when i type lsmod bvdd is listed

the error:
Error openening/initializing the selected video_out (-vo) device

sorry i fixed it now
apparently i had a mplayer-w100 installed at the same time which caused the problem

really sorry thx for your help

Okay, just to make sure there isn't any other mplayer binary somewhere on the system, your mplayer should output the following:

~$ mplayer -vo help

Ah, you were faster answering your problem, hehe. No problem!
