Hitler and the bunker have had the slow motion effect placed over them. Hitler is asked about this but he can't figure out how to solve the problem and being stuck in slow motion does not help speed things up. Later on though Hitler is the only one left stuck in slow motion.
I thought there was something about the 'Epic Sax Hitler' parody, which seemed familiar.
Anyway, I hope all is okay now that credit has been given to Smog.
Maybe, but I don't know much about how such files work on the mac.
It would be possible to convert them to a format, which works better on the mac though.
It's important to note that the video system only supports mp4, flv, mov and m4v formats.
The gallery http://www.downfallparodies.net/gallery/ also supports the uploading of videos and has no format limitations, which I know of.
