read the guides (here, doom9.org, videohelp.org, dvd decryptor forums) and manuals, then read the forums again. then post a specific question if you're still having problems. most of this stuff is out there, you just need to read the explanations. if you're not having any issues, just keep the defaults (they're defaulted for a reason). unless you have a specific issue, i don't think anyone is going to post explanations for each of the settings...they expect people to do their best to "learn" on their own before asking someone to hold their hand.
