I'm also having the same issue. I can get a static background but not video. 
It's video or words. The screen also goes black anytime I click on anything 
while running the video background where the static is on all the time.

Eu consigo visualizar o fundo estático e também o fundo com vídeo gravado 
(por exemplo, arquivo *.wmv), ambos com a letra da musica por cima, como se 
fosse legenda.
Contudo, não consigo, de maneira nenhuma substituir o fundo por vídeo ao vivo 
para exibir a imagem das câmeras que registram o culto.
Já tentei usar placa de captura externa (USB) e interna (PCI). Com os dois 
tipos de placa eu consegui visualizar a imagem das câmeras (via video mixer) 
no VLC, mas no datasoul, o fundo permanece preto.
Uso Windows 7, Java 7, Placa de captura Encore.
