kmplayer keep aspect ratio option is not always working. You need to go to fullscreen and then go back to get proper aspect ratio. Another way is to check and uncheck that option again.
which version do we speak about?
It is 0.8.4a, but i remember 0.8.4 and it was the same.
Could you please report it to http://bugs.kde.org?
This is probably not Gentoo-specific.
OK. I will try my luck there :). Thanks.
Closing as UPSTREAM.
Add a reference here if you file a bug at bugs.kde.org, thanks.
In 0.9.0_rc1 issue got fixed.
Thanks for the feedback, Michal.
