All files play fine with lqtplay (though with some of them I 
continuously get the message "consumed only X bytes instead of Y").

However now I doubt about the codec. Some of the files have the .mp4 
extension and others .mov, but all of them say

codec: H.264/AVC

in nautilus' properties/"Audio/Video" tab.

Lqtplay says "compressor avc1".

Does that mean they are H.264?
