Hi gabrielw,

the catalogs should work; I used Extras, Extras-Testing and Extras-Devel a few days ago... What is the "mistake" your system says...?

Mp4 video: not all videos are playable as it depends on quality. Try to convert the video to 800x480 or something like that; or try to play it with mplayer. If mplayer plays it, you can check if there is any slow motion or something (mplayer even warns you if your system is too slow to play the file correctly).

Cheers,

jm
