ImgBurn layer break selection?

I just got my BenQ 1655 in the mail the other day and I’m digging it so far. I use to get PI errors up in the 600-800s with my LiteON 832S, but now I’m getting PI errors below the 30s!

Anyway, I’m a bit confused as to how I should be selecting my layer breaks with ImgBurn. Can someone explain to me the padding, %, V/C ID, SPLIP, etc - or point me to some site where I can read up on it?

Any advice/tips would be greatly appreciated. Thanks.

This is the Method i use to burn dual layer discs. I like doing it this way because after picking the layer break i can preview where it will be. I usually try to place it during a scene transition. When i test the disc i know where to look for skips or freezes. Plus, it still uses Imgburn to burn.
