Hmm. I'm still getting the error here, but libavcodec-extra-52 is not

According to the ffmpeg developers, this reflects a mismatch of versions. 
Assuming they are correct, and this is not just blowing smoke, then my 
feeling is that this is caused by insufficiently tight package 
dependencies, so my suggestion would be to track it down, though this 
would probably be a comparatively difficult and thankless task even if 

It is unfortunate that the warning gives no real indication of where the 
problem lies.

I don't know if disabling the warning is such a great idea, see as it can, 
possibly, reflect underlying problems.
