Deat developers,

I know that it is not quite a bug - let's call it an "issue"; the reason  
is most probably, that Ateme used MPEG4 AVC High Profile features which  
you do not yet support:

ftp://mood.ateme.com/beta/cinderella-ateme-3000k-hp.mp4

Mplayer and ffdshow built by celtic-druid. ffdshow does not play (stall  
progress, black video). Mplayer reports:

I hope you can find out which features are unsupported, and implement them  
sooner or later. Wish you good luck!
