There's quite a lot of help with BWA settings in some of the 'How to back up Securom ...' type stickies posts. Not only on the Blindwrite forum, but look in the Alcohol and also CloneCD forums.
It will help you a lot if you can find out exactly what protection is on the CD you're trying to back up, e.g. using ClonyXXL, protection identifier, safedisc analyser etc., or look it up in one of the game protection lists that Bulk and portmac keep.
I'm not familiar with your LG burner for doing Securom, but I'm sure that someone else here will be.
Probably the reason that you don't see too many people posting about the LG burners, is simply that there's likely to be much more Lite-On and Plextor users.
I suppose there's not really a standard way of copying the latest stuff, as it tends to vary between what hardware you have and which software you use, and how you use it, but it won't be drastically different, but anyway don't be afraid to ask if you get stuck or use the search facility.
Hope that helps?
