#35 Fatal error: Class 'ffmpeg_movie' not found

[Coolguy]

I'm using php 5.1.4.4
I copied php_ffmpeg.dll in php/ext
I enabled extension=php_gd2.dll in php.ini
I add in php.ini extension=php_ffmpeg.dll, and
I copied avcodec.dll and avformat.dll
in windows/system32 directory.

It doesn't seem to recognize ffmpeg_movie. I got the error:

Fatal error: Class 'ffmpeg_movie' not found

Does ffmpeg-php extension work in php5? If not, can you fix it?

Thanks,
