Hi squadronfilms,
Thank you for the link to youtube, but unfortunatly I need to look at the film here on The Smalls. That way I can compare the original film with the one converted for playing on the site.
It seems odd that only sound effects are playing but not music. Usually a movie file has two audio channels (stereo: left + right). If you have assigned the music to one channel (lets say left) and your sound effects to another (right), and there was a problem decoding one of the channels, then it may be possible that you would not here the music.
Movies use the same audio codec for both channels, so it would be unusual that only one would be decoded but not the other. Perhaps the film was corrupted when it was uploaded.
Many Thanks,
Ady
