movie upside down

err, i downloaded a movie tonight and it’s upside down, which wasn’t the case when i previewed it.
is there any possibility to get the peopl from the ceiling and back on the floor again, meaning to flip it over ??

Do you have Nimo installed? If not, are there any other codec packs installed?

the problem solved itself, i tried watching it today again and it was fine
thanks for your help anyway
