Playback rendered not work

Hello,
I have this message when i want to render my animation :


The calculation seems to be good, its in pregress but when i want to play the render : nothing only this message :-\

In the File / User Preferences / File panel select the application you want to use as the animation player.
or use the current blender version (2.65a)

nevertheless, i need to use blender 2.61 to keep ocean simulation… vlc doesnt work, even not mplayer…

Worked for me in the past. If not working for you just open your rendered result directly from vlc

Ok i will try with it …
