HI There

I have found the problem. But I don't know how to fix it. Its inside the
patch 'patch-stream-tvi_bsdbt848.c' in mplayer's port folder. There is a
hardcoded variable "   +priv->btdev = strdup("/dev/bktr0");  ". If I
change it for example /dev/bktr7, That channel works fine.

Can anyone please help me to fix this. I want mplayer/mencoder to except my
input from console, not a hardcoded variable in the source.

Thanks
