Vc pode usar outros scripts, mas eles precisam estar em um formato específico. Como ninguém tinha perguntado antes eu não me preocupei, mas seria legal escrever um mini-how-to sobre isso.
Os scripts precisam obrigatoriamente usar os parametros WIDTH (largura destino), HEIGHT (altura destino), OVERSCAN e WIDESCREEN, e de preferencia, usar as funcoes divxresize() e divxborders com os parametros sugeridos. Além disso, vc precisa incluir os parametros necessários.
Para facilitar: se vc mexer/trocar só as linhas em verde, provavelmente tudo irá funcionar. Se vc tem algum script específico que está tentando usar e não conseguir com essas dicas, poste aqui que eu tento ajudar.
