Where to set BeSweet command line with GK

[luciusii]

I am pretty new to this and am hoping someone can give me a quick pointer. I'm using DVD Decrypter and GK and am getting very low volume recordings. Someone posted the same issue (link below) and the solution there is to alter the BeSweet command line. I've read user guides for GK, DVD Decrypter, and BeSweet and can't figure out how to set this.

I appreciate any help.

Thanks,
Luke
