Dificuldades com placa de captura e webcam com o Ubuntu 7.10

[elciocs]

Tenho uma máquina com dual boot que a placa de captura PixelView MPEG2 e a Webcam A4Tech funcionam perfeitamente no Windows XP.
No Ubuntu 7.10 são os únicos devices com problemas. Sou novato no Linux e não consegui fazê-los funcionar mesmo com a ajuda do site http://mstr.ueuo.com/bttv/index.php.
Estou postando o log dos comandos e o arquivo /root/.tvtime/tvtime.xml para facilitar na solução do problema. Grato pela atenção.
