I would be surprised if a clicking noise were the only artifact of an incorrect sampling rate on a CD. I have never used the vob input function of BeSweet, but I suggest that you try PgcDemux instead. You should end up with a stream of the type in the original VOB. Then try BeSweet using BeLight or whatever you GUI prefer to reach PCM. If it were AC3, I might just use azid from the command line, etc.
